This is a very interesting and simple toy rocket launcher. Any teenager will simply be delighted to play with her. Personally, I’m already quite an adult, and I’m happy to launch rockets from this amazing design.
The fuel for the rocket launcher is ethyl alcohol vapor. The rockets soar into the air with a cheerful clap, which looks very impressive.

Needed to make a rocket launcher

I will be making a rocket launcher from four rockets, so the items listed below can be multiplied by four. You can make one rocket.

• Disposable syringe. I took 60 ml.
• A used lighter with a piezo element.
• Two-core wire 1-2 meters long.
• Small boards for the stand.
• Hot glue gun.
• Soldering iron, utility knife, ruler and other available tools.

Making a toy rocket launcher

We take the lighter and disassemble it in order to remove the piezoelectric element, which generates a spark - a discharge that ignites gas.

We take out the piezoelectric element. This is the high-voltage generator itself. The wiring is one contact, and the second is a shiny cap on the bottom.

We take a two-core wire. It is advisable to choose one with thicker insulation.

Connect to the piezoelectric element.

Then we insulate everything with electrical tape or, better as I did, with heat shrink.
We take two needles from syringes. Here I want to warn you and suggest that you either grind off the point of the needles with a file or simply bite off half a centimeter with wire cutters. This must be done, as you may get injured during the game.
We connect the wires to the needles. These will be the electrodes that will be located inside the rocket launcher.

We solder for reliability. But this is optional.

Take the syringe and remove the plunger.

Remove the rubber seal from the piston.

Use a soldering iron to make holes in the piston.

We insert our needle electrodes into these holes.

Fill with hot glue to seal.

We take the rubber seal.

Cut off the top with a utility knife.

We put it on a modified piston with electrodes.

Fill the hole in the cylinder with hot glue. We won't need it anymore.

Cut off the skirt of the syringe barrel.

We take hard cardboard or plastic. And we cut out the following rocket flight stabilizers from it.

Bend it back a little.

You need four pieces for one rocket.

Glue it to the cylinder.

We assemble the rocket launcher.

I made four of these rocket launchers.

I'm making a stand for this whole thing. I took a rectangular piece of wood and drilled two small holes in the middle of the other half. A little later you will understand why.

Next, we take the second plank, but this time it’s smaller. Drill a hole in the center for the wires. Glue it diagonally with hot glue. See photo.

Glue all the rocket launchers.

We secure all four wires at the back with a nylon tie.

Remote controller remote control- this is also a board with piezoelements glued to it with hot glue.

This material will present to your attention a method for making simple pneumatics from syringes.

So, we will need:
- glue gun;
- juice straw;
- stationery knife;
- 2 large syringes.

We take the first syringe and cut off the spout at the very base.

Next you need to make a hole between marks 5 and 10.

Now the spout, which we cut off at the very beginning, needs to be glued to the hole. This must be done extremely carefully so as not to accidentally seal the hole.

Next, take the second syringe. It needs to be glued to the place where the nose of the first syringe was. According to the author, a conventional connection will allow air to pass through, so it is imperative to use glue for a better seal.

The pneumatics are ready. You can use it in two ways: either glue a tube and shoot balls, or do without a tube and shoot cartridges made from needles.

Everything is clear with the first option, so let’s move on to making cartridges from needles. This is done very simply. We take a needle and put it on any syringe.

We insert the tip of the needle into the turned on and hot glue gun and pull the piston, thereby sucking in a certain amount of glue.

After some time, the glue will harden and close the hole on the needle, preventing air from escaping from it.

Homemade airbrush from a syringe - an excellent helper in the household. This invention makes painting a very simple process. You can make a homemade airbrush at home, because not everyone has the opportunity to purchase one in a store, especially since the cost of an airbrush is quite high. will be no worse than store bought. In order to make it, you do not need any special skills or abilities, and the parts that make up the airbrush can be found in any home. There are two ways to make a spray gun from a syringe: without a spray gun (this method is very simple) and with a spray gun (more complex).

What is an airbrush?

An airbrush is the same spray gun ( pneumatic tool), which is designed for spraying a dye. It is used in many areas of life, but due to its high cost, craftsmen have already learned how to make an airbrush with their own hands.

Method one (airbrush without spray gun)

First of all, you need to collect everything necessary tools. To make this type of airbrush you will need:

• a disposable syringe and a needle from it (its volume depends only on the desire of the master);
• clip;
• a thread;
• fixation – adhesive tape or tape;
• small container for paint.

The needle must be removed and heated over a fire so that it can be separated from the plastic base. You need to remove the piston from the syringe, first make the paper clip flat, and then bend it at an angle of 90 °. Tightly connect one side of the paperclip and the needle with a thread. Then use tape or tape to secure the other side of the paper clip and the body. Moreover, it is necessary to fix the structure near the hole on which the needle was placed. The tip of the needle must be positioned so that it is in the center of the syringe nozzle.

After this, you should dilute the paint so that it is liquid in a small container. Take the airbrush in your hand, lower the needle into the container with the dye and blow strongly into the wide nozzle.

Such airbrushes are popularly called “rotoblowers”. To make such a device, you will need 9-11 minutes and a minimum of equipment.

Method two (airbrush without paint sprayer)

This method is identical to the method described above, it differs only in a few details.

To make it you will need:

Position of the spray gun: a – walls, b – ceiling.

• gel pen refill;
• disposable syringe + needle;
• rod section ballpoint pen;
• glass or plastic bottle, container for coloring emulsion;
• hot melt adhesive.

The entire process of assembling the airbrush occurs in several stages:

• cut off the writing part of the pen with a cone;
• cut off the sharp part of the medical needle;
• first dip the needle in hot glue and insert it into the cut rod so that its tip is visible from the metal part of the rod;
• top part the syringe is attached to the bottle (a rod with a needle must be inserted into the body);
• make 3-4 holes in the lid for air access;
• The distance between the tip of the needle and the pen can be determined experimentally.

One of the advantages of this airbrush is the easy replacement of the reservoir.

Airbrush with paint sprayer

In order to make a more convenient homemade airbrush, you will need the following parts:

• pens (3 ballpoint pens, 2 gel pens);
• pencil;
• an empty metal bottle (you can take a bottle of cosmetics);
• syringes (2-3);
• hard wire;
• bolts 2 pcs. 3 mm each;
• nipple;
• small needle – 2 pcs.;
• glue.

First of all, you need to assemble the cartridge and needle retainer. You need to make it from a syringe, a gel pen refill, a fountain pen spring and a bolt. Remove the piston from the body, lower the spring inside (it should be next to the thin nozzle), make a hole in the rod and insert a bolt, and they should be perpendicular to each other. This structure is subsequently inserted into the housing.

In the body of the ballpoint pen, you need to make holes on both sides with a hot knife: one is smaller and more round (about 0.5 cm), the second is larger and longer (about 2 cm). Next, a piece of wire must be bent into the trigger stop. Heat a needle suitable for the diameter of the wire and make two holes in the housing for the bent wire, insert it into the housing.

The next step is to prepare 4 pieces of wire 6 cm each and bend them at a right angle. These segments should be secured air corps, or rather its valve (made from a piece of the body of a ballpoint pen).

Then you need to insert the housing that holds the needle directly into the spray gun. It must be inserted without special effort. The length of the gel pen rod is selected so that the rod rests against the bent wire and the spring is compressed. To connect all the parts you can use epoxy resin, hot glue or regular superglue.

Next thing you need to do air valve airbrush, it will consist of a syringe without a piston, a needle, a spring, a piece of tube from a cylinder (air freshener), and a nipple. All parts must be connected, pre-treated with glue.

For the trigger you will need an antenna and a piston cap. It is necessary to connect two sections of the antenna to the cap, and insert a match with glue already applied to it inside. All parts also need to be coated with glue so that the structure is strong.

In order to make a paint sprayer for an airbrush, you need one syringe, an iron part of a medical needle, a part of a rod with an iron tip, and an air supply hose.

The container for the color emulsion will be a deodorant can, or rather its upper part, which needs to be cut off with a knife.

When all the parts are connected to each other, the spray gun can be considered ready. It’s not difficult to do and doesn’t take long, the main thing is to have the desire. But if you don’t want to bother with a complex airbrush designer, you can completely use the first and second methods. They don’t take that much time, and the parts for making them can be found in any apartment or house.

There is another way to make an airbrush with a spray paint from a deodorant can. Moreover, the empty can will act as a spray bottle for soft dispersion of paint or any finely dispersed chemical substance. For production you need:

• empty can;
• large capacity syringe;
• vinyl tube with a diameter that will fit the small nozzle;
• compressor to create pressure in the cylinder;
• gloves.

Remove the deodorant from the deodorant can plastic valve. Place a vinyl tube on the syringe, as close to the base as possible, and cut it so that it can later be put on the nozzle of the syringe, but so that there is room left for pressing the valve of the can (that is, the length of the piece of vinyl tube should be approximately 0 .5 cm). Dial liquid paint and connect a piece of vinyl tube to the can. In this method, the syringe acts as an element for filling a can of paint. In order for the paint to get inside the deodorant can, you need to press the nozzle of the can and then the plunger of the syringe. It is easy to calculate the volume of paint to be refilled; just look at the volume of the can and the capacity of the syringe. For example, the volume of a can is 150 ml, a syringe is 10 cubic meters, which means that you need to pour 5 volumes of paint into the can. It is very important between refills not to forget to first press the cylinder valve, that is, close it, and only then remove the syringe.

It is necessary to make an adapter from a plastic cover of a medical needle that will connect the cylinder and the compressor. You need to make a small hole in the sealed part of the case, and insert the open part into the compressor tube. Next, turn on the compressor, put the adapter on the can, press on its nozzle and fill with air (about 2 kg of air per 150 ml can). Before painting, put a plastic spray bottle on the can and shake it.

For quite a long time, anglers have had baits such as poppers in their arsenals. This tackle shows excellent results when fishing for pike, therefore it has become widespread among fishermen in our country.

You can purchase in specialized stores various options poppers, for any color and taste. However, for anglers who like to put their hands to it, I want to offer an example of a popper from a disposable pharmacy syringe.

At minimum costs You can get a homemade, pretty decent catchy popper.

To make a syringe popper you will need the following materials:

• syringe five cubes;
• wine bottle cork;
• two wires;
• two tees with winding rings;
• steel balls that can be removed from the bearing.

The process of making a homemade syringe popper with your own hands:

Let's get down to the task at hand - making a popper. We disassemble the pharmaceutical syringe and cut off unnecessary parts (we cut the nose, the stem into pieces and use only the middle). The actions can be seen in the photographs.

Cylinders are cut out of a wine cork, which are the size of the syringe and will be tightly inserted inside. To do this, use a knife to cut off excess pieces in a circle until you get required size. To avoid mistakes, you can draw the cut location with a ballpoint pen.

Then we push a small cylinder of cork into the syringe to the very end, carefully pierce a hole in it for the wire. Next we send the middle part from the cut rod. We also make holes for the wires in the remaining cylinder, as shown in the photo.

We pour steel balls inside the syringe and push the stopper. We twist the free ends of the two wires and make a ring for attaching the fishing line. We also bend the remaining free ends of the wires and create rings for attaching hooks.

All that remains is to attach the tees with winding rings and a homemade popper - the syringe rattle is ready. You can go to the river and try to catch a predatory pike, which loves to attack such baits.

Homemade syringe popper is ready

All that remains is to add that when making a homemade popper from a syringe with your own hands, you can add something of your own and modify the homemade product, which will certainly lead to an improvement in its quality and catchability. You can add red hairs to the tees, you can also put chopped multi-colored foil inside, or you can come up with your own original equipment for this bait, or an original color.

Fill eclairs with cream. If there is no such product, then you can create it yourself. How to make a pastry syringe with your own hands? This work can be done using various available materials.

Terms of use

The set with a culinary syringe has various attachments:

• Smooth cut.
• Oblique cut.
• With teeth.
• With stars.

The attachments allow you to create wonderful culinary masterpieces. Syringes are needed to decorate cakes with various designs - flowers, leaves, inscriptions, mesh, borders. To create a rose, you need to take a piece of sponge cake, align the edges, put it on a fork and coat it with cream. Then you can do the petals. You need to take the fork into left hand, gradually turn over, and with the right hand - create petals. You need to make small petals in the center, and larger and higher ones at the edges. Using another fork, the rose is removed and placed in the desired place on the cake.

The cone-shaped nozzle is used to create leaves. A device with a flattened end allows you to get bows, ruffles, and lambrequins. There are attachments for creating smooth and grooved stripes. They allow you to create a wicker basket. A narrow nozzle with an even cut is used to create an inscription and obtain a lace pattern, smooth, wavy lines. You can make other decorations as well. The cake will be more beautiful if you use different colors.

Polyethylene

You can make a confectionery syringe from polyethylene with your own hands. The material should be dense and transparent, with a zip fastener. For this work you will need scissors. The procedure is performed based on the following steps:

• You need to open the package and fill it with cream.
• Then you need to fasten the clasp or secure the bag with a knot.
• Then you should cut off the corner of the bag.

This product is not considered multifunctional. For example, it is unlikely that it will be possible to achieve the same thickness. This also applies to figured jewelry. But if there is no other choice, then such a bag is suitable for decorating a cake.

Paper

A DIY paper syringe provides more possibilities. The base can be pastry parchment. For thick paper, a shaped corner can be used as a nozzle. To get the product, you need to cut out a triangle and roll it into a cone.

There should be no gaps between the layers of paper, as cream can pass through them. Then you need to fix the edges on top, bending them towards the center. The bag should be filled to the top. Be sure to cut off a corner: the hole will serve to squeeze out the cream. The device can be used to decorate cakes.

Plastic bottle

DIY confectionery syringe from plastic bottle will allow you to create beautiful roses and other decorations. You will need a shaped nozzle from a plastic bottle. To create the product you will need a knife, marker, and pastry bag.

The procedure involves performing the following actions:

• Cut off the neck of a plastic bottle.
• Draw the desired pattern on the lid and then cut it out.
• It is necessary to screw the lid on the neck and secure the shaped nozzle to the made bag.

This completes the DIY pastry syringe. Using this method, you can create several attachments so that you can make various cake decorations. In addition to the lid, the attachments can be nasal spray caps.

Fabric use

You can make another pastry syringe with your own hands. It will be much easier to do this job with a photo. The device can be sewn from fabric. The material should be easy to wash. It is advisable to purchase White color, since colored ones can shed. Dense teak is ideal, as it is durable, natural, and easy to disinfect at elevated temperatures..

You need to cut a triangle out of the material and sew 2 sides. The size of the product can be any, the main thing is that the required portion of cream fits into it. The top should be cut to the size of the attachments that will be used. Both purchased attachments and homemade ones are suitable for this.

The seams need to be turned up and hemmed. It is advisable to work on sewing machine, because this way the product will be reliable. The device is ready to decorate the cake. It can be reused if washed and dried after each procedure.

Using a mayonnaise packet

A mayonnaise bag will help replace a pastry syringe. It is necessary to cut off the bottom of the package and then wash the product inside and out. The other part has a hole for squeezing out the cream. This option will allow you to perform even simple, but beautiful jewelry. Packages from other products, for example, condensed milk, jam, mustard, are also suitable for this. Only the product must be absolutely clean.

Applying a file

To obtain a pastry device, you can use a stationery file. This product is more suitable for one-time use. Its corner part must be filled with cream, and the corner must be cut off. By pressing on the contents, you can decorate the cake.

Oilcloth

To create such a product you will need a triangle of oilcloth used on the farm. It is connected with wide tape to form a cone. The corner needs to be cut off so that the nozzle is secured in the hole. This simple device will be used for decorating cakes. Its only drawback is that such a bag is disposable.

Using any of these methods you will get a practical DIY pastry syringe. You can create beautiful cakes and pastries at home. To make decorating confectionery products easier, you should use the following tips:

• When using a bag, patterns should be made with the left hand, and with the right hand you should hold and squeeze it a little.
• You don’t need to immediately start creating complex landscapes; first you need to learn how to create something simple.
• Dots should be applied with a round nozzle.
• The stars are made with a figured nozzle.
• To prevent trembling from tension in your hand when working, use your left hand under your right hand as a support.
• When creating small patterns or inscriptions, the nozzle should be kept close to the baked goods.

Making cakes is interesting activity. It is important to adhere to accuracy and caution. The modern confectionery industry is rich in a variety of decoration products. Store-bought products contain dyes, preservatives, and additives. If you learn how to make cakes yourself, you can enjoy delicious and healthy homemade baked goods. A handmade bag will help decorate your masterpieces, making them even more appetizing.
