I would burn... well. Wood. It smells great when you have a campfire or bonfire going, and I can't think of many chemicals I would burn that wouldn't explode.
I would like to set a fox on fire... hah, get it? because, you know the fox... and the fire... come on, you know... the fire and the fox... you know, you put them together... right? hah! it's firefox! haha you know fire-fox. hilarious! I wonder if there is anything more to explore... you know?... come on guys, you know this... again. What ever I don't have time to explain.
