I know that long nose piezos don't hurt. How many volts are they? But do BBQ
igniters hurt? What are the chances of getting shocked? Can I buy BBQ igniters?

i said the pocket thing just to describe the size.

would using a lantern sparker and propane be safe in a mini combustion? and by mini i mean small enough to fit in a pocket. its going to be made out of metal.

LOL! I used to play that game online everyday. I owned with the G-Bomb.

Can I just by those small cheap motors and power them by a series of 9volt batteries? Will the RPM increase with more battery volts?

I don't like the idea of using an angle grinder for three reasons. 1. They’re too large and heavy 2. They’re AC powered (Not Portable) 3. They’re Expensive I would go with an r/c type motor: they’re small, powerful, and battery powered. You don't really need too much momentum or with as much power ...

Well I was looking in to this...

And you can get over 10k RPM just by shaking it. I plan to copy the style of the gyroscope and power them by some good motors.

I'm going to build a new type of BBMG rather than the vortex or cloud design. It's going to be powered by two wheels that spin at a fast rate and the BBs just pass through it. I need any suggestions on what I should use for the wheels, motors, and batteries. And if the wheels were spinning at 10,000...

It should be judged based on look, range, accuracy, and plausibilitiy.

Lol. I used to be a nerfer and it took about an hour to make micro stefans (custom nerf darts).

So I'm guessing it'll take around 25 per hour for these. Still looking for a material for mass production though.

I guess I don't really see the point in making "bullet cartridges" for potato cannons. And I really don't see the point in mixing a burst disc with a "bullet cartridge". If you're going to build cartridges make them with propane or some other type of flammable gas. 1. Full-auto and semi-auto is pos...

http://static.howstuffworks.com/gif/machine-gun-bullet.gif I was thinking of making bullet catridges except the propellant would be a high-pressured gas and the primer would be a burst disk. The hammer would pierce the burst disk and there she blows! But just a few questions. Which gas should I use...

What's the best gasoline:styrofoam ratio for napalm?

Lol petroleum jelly is fireproof. Not flammable...

If it would be pneumatic then I would have to use a gas. And gas compresses. Meaning no hopping...
