WATERVILLE — Twenty-two adventure girls recently experimented with Colby College professor Lisa Lessard and Hardy Girls Healthy Women Board Member Jennifer Hale for a day of physics magic.

Participants learned about friction, gravity and electricity as they experimented with different materials such as glass, plastic and wooden rods rubbed against silk, fur and plastic bags. They also had fun rubbing balloons on their head to see what static electricity does to hair.

Batteries and light bulbs were connected and lit as they experimented with charges and electricity. At the end of the sessions, participants had a chance to test their boat-building skills by trying to make clay boats float.
