This is very simple and cheap trick, great to impress the friends and in parties.
all you need is a matchbox, 3 matches and something to ignite the trick (a lighter or a matchbook and a match)
Step 1: Preparation
Open the matchbox a little, put two matches in the matchbox standing up with the starter up, close it and joint the tips outside. Place the third match with the starter on the other matches.
Step 2: Light It Up!
Light the matches using the other match and let the matches burn. While they burn, the third match will go up and down and most times it will stay in the air when the matches stop burning.
