Start your class with this easy-to-perform, "wow-factor" demonstration. 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.
Also included are instructions and materials to perform an alternate demonstration where a toothpick is inserted through the mesh screen after the card has been removedand still not a drop of water spills.
This demonstration helps students meet the Next Generation Science Standards Performance Expectation:
Kit materials may be used indefinitely.
