Watch this vidoe to know how to make Flash Paper and ENJOY !!!
http://www.youtube.com/watch?v=5C8vatxCeds Here's how to make it. Let it dry for about a week. Once it is rock hard and white, crush it up (via. coffee grinder, mortar and pestle, or a hammer) Other info called for by the annotation: Spread out the paste and let it dry for about a week.
how to make a homemade bb gun from general household items easy!!!!!!!!!!
This gauss gun is powered by a 660v, 670μf capacitor bank. The capacitor bank consists of 22 capacitors that came from disposable cameras. The coil was made from 14gage wire, 102 turns total, 6 layers, and 17 turns on each layer. I calculated the inductance of the coil to be about 196µH. I cut a piece of nail for the projectile and the barrel is a straw. The projectile weighs 4.18g and is 3cm long. There is 1mm between the inside of the coil and the outside of the projectile. I used 6 diodes (three parallel sets of two diodes in series, total surge rating of 1000v, 900amps) in anti-parallel with the capacitor bank, to protect the capacitors from reverse charging. During the firings, I killed four diodes and welded open two switches. The switch that I am using now welds shut every now and then, but because of the switch design, you can break the weld by forcing the switch into the off position. I calculated the velocity of the projectile to be about 25m/sec. To do this, I shot the gauss gun at a piece of cardboard 5.5m away. Using the hole in the cardboard, I calculated the drop of the projectile, and then the velocity. The gun will make holes in soda cans. One of my friends wanted me to shoot the gauss gun at him to see what it would do. I decided it would be better to shoot it at a thawed chicken instead (:

It's completely safe. Try this for your friends computer, or even better, for public school computers. Just imagine every computer in the class shutting down :D
