flying brain
This is a favorite trip toy of mine. One would take a single piece of newspaper, forming a ball with air in it and twist the bottom. Then, one light the twisted up part of the bottom and the ball will fill with hot air and rise. As it continues to burn, the ball, now the brain catches fire while floating high abovet and it looks like blood vessels in a brain pulsing with light. Pretty damn trippy!
When playing with with a flying brain, you should probably have some water close by dude......whoa man thats trippy!
