Did this happen before?

one more bug - acid dissolves insulation, nuke explosions and plasma burn it

p.s. sorry for my english

Isn't that what acid would do? And insulation is supposed to be able to catch fire, it's not a bug either.

sorry for not posting...
***Stickman Glitch***
Put stickman in a small box, and can be made of anything, or any thickness.
Make stickman jump against the right wall of the box.
Keep jumping.
Keep holding right so you hug the wall while jumping.
Eventually he'll stick his leg in the wall, and fly through.

Do you really crave attention so much that you need to claim the finding of a bug?

No, I just felt like giving it a title and make it proper.
