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 removed—and still not a drop of water spills.

This demonstration helps students meet the Next Generation Science Standards Performance Expectation:

  • HS-PS1-3: Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.

Kit materials may be used indefinitely.
