Static electricity occurs when you rub two objects together. This causes friction. It is an actual power. The connection is a charge of electrons moving from one object to another caused by friction. |
 |
|
Friction is needed to create static electricity. |

Friction made by rubbing yarn against the balloon! |

|
We made static electricity by rubbing a balloon on hair. The hair stood up and danced as we moved the balloon above our head. |

We were trying to get Rice Krispies cereal to react to static electricity. We took a clear plastic cup and put in 6 Rice Krispies cereal. We covered the cup with plastic wrap. We rubbed a balloon to create friction and then took the balloon to the top of the cup where the plastic wrap was over it. We wanted to see if the Rice Krispies floated up. It didn't work. We concluded that we didn't have enough static electricity to make the Rice Krispies float or jump. |
 |
Here students rubbed two balloons together on top of the cup to try to create a stronger charge. It didn't work either. |
 |
What we did to make it float up! We rubbed a balloon real hard on the top of the plastic wrap for about 20 seconds. Then 5 of the Rice Krispies floated up to the top of the cup. It worked! |
