that is explosive that i can make?

Uhhhh, lighter bomb, light a fire, throw a about a dozen lighters into it and back up, it makes a rather large fireball, gave mr brother second degree burns whern he didn't back up fast enough... and that was one lighter! Ohh, and it throws little peices of plastic around and they hurt like a bitch. a bit shrapnel like.

or you could buy fireworks, gunpowder, drano and aluminum foil, if they have saltpeter stump remover you could mix that with a sugar for a smoke bomb. Buy those mini 12gram Co2 tanks and light a few on fire. They blow up well. You could make a pvc pipe bomb, come to think of it, walmart has quite a few chemicals and minor explosives that you can use. Look up other stuff on the site and decide whether or not you could buy it at walmart. Go to walmart.com to see if they have it first though anad be over 18 to get a lot of it.

lol that almost exactly what i was about to go buy at walmart.
