...Chinese Wish Balloon. Yes they fly and of course your wishes do come true eventually. All low tech and pretty simple and primitive but hugely satisfying. Simply light the blue touch-paper, struggle for a few moments and then let it go, and it does fly and you get a rush, particularly so when it floats into a commercial flight path, ("but we are five miles away!"). Somewhere in the distance I swear I could hear Simon Dupree and the Big Sound.
Thankfully no cats, passing rodents, teenagers or concerned adults were injured or overly upset during this historic event. I want to do it again.
