These are very short: only 5 seconds long. If you don't know how to play them, see the instructions at the bottom of the page.
This first video shows some guests causing the balloon to levitate. First grade classes from the elementary school accross the street from the middle school where I teach visited, hosted by my teenage students. We had several rooms set up like a hand-on science museum. Once the kids realized they had to move the hairdryer slowly, they could do it. Although young kids usually make it float straight above the hairdryer, you can still levitate the balloon at a 45 degree angle from the hairdryer. You can't really tell the balloon is spinning in this heavily compressed video, but it is.
In this second video, one of my students is attempting to land the spinning balloon in a container--no easy task. It makes one appreciate the difficulty of landing a helicopter in windy weather. Here is another video of a student actually getting it in.

You will almost certainly have to hit play a second time if you have a dial-up internet connection. If you still can't get it to run smoothly, you will have to right-click, then "save file as..." or something similar to that. Take note of where you are saving it. They are short and highly compressed, so they won't take long to load. Even with a fast connection, save the file like that if the picture is jerky. To play the file, find it and double-click on it. It will play in the default media player.
