I have little experience with airsoft so perhaps you desire this effect, but the design you posted will only hit people directly above/infront of it(if I only knew how this is applied...) and a few feet to either side, it will not scatter a lot. Also the bbs will fall out if you trip and drop it or ...

When using a vacuum remember that the egg has a bit of air at the top(the reason you poke a hole into it before boiling!) that would cause it to burst in a vacuum, to avoid this you can either; -Remove the shell by letting the egg sit in vinegar. -Poke a hole into the flatter side of the egg before ...

Torsions springs are used to open the boots in some sedans, have a look at an Auto shop or something similar.

In theory that sounds like it would work, in practise i am afraid that unless the pressures you are using are very high and the projectiles heavy and the barrel long, it won't work. I am sure you can work it out with some formulas, finding out how much energy it would take to push the piston back(re...

But I agree to a brain storming thread of some sort where anything spud related goes(according to rules and minmal common ...

Look mate, in a soda can with beer the amount of compressed gas(=stored energy) is far smaller than in a can with only compressed gas. Now if the first one bursts then you get wet, if the second one does you can pull shrapnel out of your hand. Say you drop it, or the metal simply fatigues. You might...
