0swolleneyeball 9 years ago ReplyUpvoteI put alot of axe into a 2 liter bottle and lite it, and discoverd that if you tip it over the flame some how pulls in alot of oxegen and the small fire became and sounded like a jet engine. no thrust but very wierd the see unexpectedly ive also took a ping pong ball and coverd it in rubbing alchohol and tryed playing in the dark with it. doesnt work well, you cant hit it too fast or goes out, play too long and it ether starts to melt the ball or just goes out. Too much effort. One thing that does work is wrap a marble in several layers of cotten cloth and sew it together best ya can and put rubbing alchohol on it and light it. you can pass back and forth with tenis rackets. use metal wire.
