A mate of mine had one last week, not knowing what was in it. After he dropped it, he wandered off for a dance, came back 45 minutes later sweating like a muh-fu**er and just said "speed-bomb".
The funny thing is, this dude loves his speed bombs and seemed to be having a great time with no ill effects.
Approach with caution......
