Who hasn't shot chewed paper through a tube from a disassembled fountain pen into the back of a classmate's head at school? But this simple device is a toy copy of a wind pipe - a weapon that at one time terrified the colonialists. Such a projectile is the prototype of all modern types of pneumatic weapons. For different nationalities, wind pipes were made in different ways. You can make a blowpipe out of scrap materials.
Instructions
Step 1
Take a seamless metal pipe with an inner diameter of 1.5-2 cm and a length of 150-200 cm. It is best to use an aluminum or duralumin pipe. The pipe must be straight, without bends or deformations along its length.
Step 2
If you want a more powerful weapon, make a tube of two or three sections. You can disassemble such a collapsible tube in a matter of minutes and put it in a travel bag. Fix the sections using a connecting tube of a slightly larger diameter. The connecting tube is put on at the junction of the parts and tightened with clamps. Fit the clamps with screws.
Step 3
Use a syringe or plunger to make a mouthpiece. It can be round or rectangular. The purpose of the mouthpiece is to keep the lips from joining the metal. You can make a mouthpiece out of a plastic cork from a champagne bottle. To do this, cut off the bottom of the cork and push it tightly into the tube.
Step 4
Close the tube section facing the target in the stowed state with a suitable size plastic cap. The cover will prevent the inside of the tube from getting dirty.
Step 5
As shells, you can use bamboo skewers and even paintball balls. Here, endless horizons for creativity open up before you. The length of the boom can be 10-30 cm. Make the rear end of the boom somewhat thicker, slightly smaller in diameter than the inner diameter of the tube. This will create the necessary pressure when the projectile is blown out of the tube.
