$20.00Price

Flood the classroom with discussions about surface tension, air pressure, and adhesion as students explain why a card "sticks" to the opening of an inverted jar of water and why the water does not spill out when the card is removed. Challenge students' observational and critical-thinking skills with this classic discrepant event. Kit materials may be used indefinitely. Includes instructions.
