Toy rocket launcher from syringes with remote control
This is a very interesting and simple toy rocket launcher. Any teenager will be delighted with the game with her. Personally, I am already quite an adult, and then with joy I launch rockets from this amazing design. Fuel for rocket launchers are ethyl alcohol. Rockets soar into the air with a perky slam, which looks very impressive.
It will be needed to make a rocket launcher
I will make a rocket launcher of four rockets, therefore, the fashion below is multiplied four times. You can make one rocket.
Disposable syringe. I took 60 ml.
Used a lighter with a piezoelectric element.
A two-core wire 1-2 meters long.
Small ones stand plates.
Hot glue gun.
Soldering iron, stationery knife, ruler, and other available tools.
Making a toy rocket launcher
We takelighter and disassemble it, in order to pull out the piezoelement that generates a spark - a discharge of igniting gas.
We take out the piezoelectric element. This is the high-voltage generator itself. A wire is one contact, and the second is a shiny cap from below.
We take two-wire wire. It is advisable to choose with thicker insulation.
We connect to a piezoelement. Then we isolate everything with tape or, better than me, with heat shrinkage. We take two needles from syringes. Here I want to warn you and offer either to whittle off the needle point with a needle file or just to bite off the floor a centimeter with pliers. This must be done, because during the period of the game you can get hurt. Connect the wires to the needles.These will be electrodes that will be inside the rocket launcher.
Solder for reliability. But this does not necessarily .
Take the syringe and take out the piston.
Remove the rubber seal from the piston.
soldering iron to make holes in the piston
put in these holes, our needle electrodes
Fill with hot glue to seal.
Rubber sealant is taken. Cut off the top with a stationery knife.
We put on the modified piston with electrodes.
Fill the cylinder bore with hot glue. We don’t need it anymore.
Cutting the cylinder skirt of the syringe.
Take a hard cardboard or plastic. And we cut out from here such flight stabilizers of a rocket.
Bending back slightly.
We need four pieces per missile. Glue to cylinder.
Putting together a rocket launcher.
I made four such rocket launchers.
Affairs stand for the whole thing. I took a rectangular plank and drilled two small holes in the middle of the second half. You will understand why a little later.
Next, take the second plank, but smaller. We drill in the center of the hole for wires. Glue with hot glue obliquely. See the photo.
Glue all the rocket launchers.
Behind the wires we fasten all four wires with a nylon coupler.
Remote of the management station is also a board with piezo elements glued to it on a hot glue.
The rocket launcher is ready.
Getting down to the game. To fill our rockets with fuel we take perfume or cologne. We remove each cylinder and pshikayem spirits into it 1-2 times and then we put the rocket back on. Inside there is now a mixture of alcohol.
In order to launch a rocket, click on the piezoelectric element.Inside the rocket, a spark jumps and the mixture ignites. As a result, the rocket takes off. Everything is accompanied by a small pop. The rocket flies 5-10 meters.
Watch the video
More detailed instructions for assembling and testing the rocket launcher can be seen in this video. In the manufacture and game do not forget about the precautions. Although it is a toy, you can harm yourself if you neglect it. So do not forget that all responsibility lies only on you.
