I seriously, would like to invent something great before going to the heaven. These are the few things I made - Wood Factory - Smoke Grenade (out of kno3) - Hand Grenade (w/o using gunpowder) - Remote controlled car that will blow up whenever I want to Wood Factory cuts wood using Nichrome wire and such, and you should be able to understand other stuffs I mentioned above. Anyone with me, would also like to make something great out of tools we are using everyday?
