xMistuhEthan Posted January 21, 2010 Report Share Posted January 21, 2010 Hey. I'm Ethan. In need for a 8th grade science project. Is it possible to use kinetic energy (Airsoft gun & bb) to power a light bulb? If it is. Could any experts give a tut on how I can do that? Thanks.

Turtle Posted January 21, 2010 Report Share Posted January 21, 2010 :eek: ouch! have you checked with school officials to be sure this is ok? gun+school=trouble? theoretically though, attach a "paddle wheel" thingy to a small electric motor and wire it direct to a flashlight bulb. shoot impact the paddle wheel with the bb projectile. i think that ought to light the bulb briefly. :phones: now, again, this has bad-idea written all over it. perhaps you can launch a ball of foil from a moustrap and hit the paddle wheel? shoot a spit wad outa a straw? (mmmm...maybe not good either. :doh:) drop a rock straight down on the paddle wheel!! dude, you're gonna shoot out your eye! >> NRA Gun Safety Rules Buffy 1 Quote Link to comment Share on other sites More sharing options...
UncleAl Posted January 23, 2010 Report Share Posted January 23, 2010 If the bb were a strong magnet Magnets : United Nuclear , Scientific Equipment & Supplies shoot it through a tightly wound narrow solenoid connected to a tiny LED (no ballast resistor). With a bb machine gun and a dry film capacitor you might pull it off... if the projectiles had aligned poles. if not, the induced voltages average to zero.
