User blog:Carly.noneya/Things exploding?

When I was playing Tekkit with a friend, I was standing on a chest and he was coming to me and it randomly exploded and broke our alchemy chest, 2 RM furnaces, and Condenser. Then another time I was writing on a sign and I randomly exploded and broke the sign and part of the building next to me. I know this wasnt from a creeper, due to the fact the first time it happened The person I was playing with was watching me and coming torwards me. I was woundering if anyone could know why this is happening? Thanks
