If you learn these amazing party tricks, you'll always be the life of the party. They're all super fun, easy and can be done with materials found in a normal house.
Most people have at least a few old CDs laying around their house that they don't use anymore. Get permission from the party host to completely destroy one of these and also grab a lighter. Scrape off the aluminum coating on a section with a knife until it is clear. Then heat up that part with the lighter. Before it cools down, hold up the CD and blow against it. A very impressive long plastic bubble will shoot out of the CD, so make sure no one is standing directly in front of you!
