Guard Dog Burglar Alarm!
If you are at a red light and no one else is there waiting at the intersection and lets say you wait there like this for about 5 minutes. Do you run the red? If it was red for 15 minutes would you really sit there for that long with no one around? what about 1/2hr or 1hr?

How to Make Vortex Cannons
I made a pair of these using 1/2" copper tubing and they work like a champ! Had to first JB Weld a washer onto the end because the opening is too big to stick a 1/4" nut on a 1/2" tube. I also just skipped the heatshrink tubing entirely, and soldered the connection to the glow plug instead of using a butt splice.I found it works best with a very very small amount of flash cotton followed by a decent size wad of flash paper crumpled not too tightly and stuffed down the barrel. It's important to stuff it down to the end of the barrel pretty good too. If you use too much flash cotton, it will eject the flash paper before the paper has a chance to ignite. If you use just flash paper without the flash cotton, you get more of a flamethrower effect instead of a projectile.

Same here... Maybe in your above hack, you should stress the exact kind of Energizer battery because I just destroyed a 9 volt battery and that black, gunky stuff is hard to wash off. But, thanx anyway
