What You'll Need
How We Did It
Next, we needed to get a nickle upright.
Hmmm.... let's see if we can find a flat spot on our table! Roll, chase, giggle.... roll,chase, giggle.... Eventually we were successful, and decided that this table would be a fine one for our investigation.
Then Maddie picked up the balloon, and rub-da-rub-rubbed it across the back of her freshly washed hair. This negatively charged the balloon....
and we brought our statically charged balloon closer to our cup.....
The toothpick moved! The positively centered toothpick is attracted to the negatively charged balloon, which makes the toothpick rotate and swing atop the coin! Maddie played around with charging up her balloon and trying to move the toothpick from different distances.
