It’s been raining for about two weeks straight in Minnesota and my kids are climbing the walls. Yesterday, they built an amazing fort and played in it for an hour before they came to me asking what they could do next.
This easy experiment kept them busy for a little while.
Take a plastic comb and comb your hair a number of times, or rub it on some tissue paper. Tiny charged particles called electrons will collect on the comb and give it a negative charge.
Now, run a very thin stream of water from a faucet and hold the comb next to it without actually touching the water. What happens?
The stream of water is positively charged and is attracted to the opposite (negative) charge of the comb, pulling and bending the stream of water toward the comb.
Many more experiments to follow in the next few months! We’re planning a summer of science between our many sporting activities, so get those science notebooks ready and follow along with us!
