Had a good time at a party out in the woods of New Hampshire last night:
Note the hollow tree trunk upright in the bonfire. It burns from the inside out with a jet of flame shooting out the top. Very cool:
Here's a can of bug spray in the hollow tree trunk after the trunk fell over. Yeah, it was that kind of party. Actually, I think it was mostly empty, and just made a rush of sparks for a few seconds.
