Surface Tension - Amazing Upside Down Water (Arpa Ghazarian)

Questioning Script

Prior knowledge & experience:

Why does water collect in drops? Why can water travel up a plant stem?

Root question:

Why is it that the water doesn't pour out from the jar with the wire mesh lid when you turn it upside down?

Target response:

1. Surface of liquid behaves as if it has a thin membrane stretched over it. The surface tension

"membrane" is always trying to contract.

2. Cohesion causes this effect.

Common Misconceptions:

Water will pour out of the jar because the lid with the wire mesh has holes. Water can escape form the holes.
