This device is derivative of the Hadouken from Street Fighter. It allows a person to have the video game power of throwing fireballs. It challenges the idea of letting reality rule your life...

Thanks to Sublime for his original Pencil launcher design.
This can be strapped to your arm to fire small projectiles or trigger aerosol cans. It is small enough to fit inside of a sleeve. I also remade the firing latch to require more force to trigger. It fires via pullstring. Ideally you would tie the string to a 3d printed ring to place on your finger for triggering. This would ensure that you had to move your hand out of the projectiles path in order to trigger the device. Ie if this is mounted on the bottom of your wrist you would have to pull you wrist back and away from the gun to shoot it ala spider-man. If it's mounted on top of your wrist you would drop your hand away from the gun to fire it.Always use the safety pin from the original pencil launcher to lock the launcher when not planning a shot.
MRK 2 Barrel Features Glueless assembly and a reinforced trigger post.
Thanks again to sublime for cleaning those latches up for me.
MRK 2 Piston features an extended handle for better grip on the safety.
MRK 3 Piston features thicker arms for stronger rubber bands and better alignment.
Use a rubber band attached to the rectangular post next to the latch to keep the latch level. (Double it over or use two to make sure it is taut. Tie a string to the latch and route it behind the bottom post before stringing it out the front of the launcher. Use velcro straps in each of the flat holes in the bottom of the barrel to strap it to your arm. Pull the string to fire.
To use with aresol cans ( and manually operated spray bottles) resize until the inside diameter of the barrel is slightly larger than the diameter of your chosen can.(Silly string for web launchers, Pepper spray for nonlethal self defense, and Butane for a flamethrower.You could also launch paintballs or paintballs filled with mace. Hows that for a 3d printed arms race?) Don't forget to resize along the length of the gun to match the height of the can. You then need to create a plastic disk with a hole in the center that the small part of the aerosol nozzle will fit into. The diameter of the disk should match the diameter of the bottle. This disk will go inside of the barrel just behind the muzzle. I am not going to upload the ignition system to the flamethrower part for safety reasons. (If a kid is clever enough to finish building it they are probably clever enough not to get burned.) If you are able to get it working from there you should be able to make it easily. I'll be posting a video soon of a version I am printing that works with a manual spray bottle and everclear to create a real life hadouken.
FIRE IS DANGEROUS DON'T PLAY WITH IT. ABS IS VERY FLAMMABLE AND YOU REALLY DON'T WANT A HUNK OF BURNING PLASTIC TIED TO YOUR ARM I AM NOT RESPONSIBLE FOR HOW YOU USE THIS DEVICE AND THE USE OF FIRE WITH THIS DEVICE IS NOT RECOMMENDED
