How to make a homemade barometer

1. Cut the end off of a 12" balloon, about an inch from the stem.
2. Stretch it over the top of a glass and pull it tight. Secure the balloon.
3. Cut the end off of a straw so that it has a point.
4. Tape the straw to the center of the balloon.

The straw will rise during a time of high pressure and fall during a time of low pressure.
