Amusing Surface Tension Experiment

The video explores a science experiment using a clicky pen spring in water. Initially, the spring floats due to surface tension, as the tightly bonded H2O molecules create a net on the water's surface. The video humorously explains the concept of surface tension and how soap can disrupt it by breaking hydrogen bonds, causing the spring to sink.

What is the initial step in the clicky pen experiment?

• Add soap to the water.

• Heat the spring.

• Fill a cup with oil.

• Place the spring in a cup of water.

Why does the spring initially float on the water?

• The spring is hollow.

• Surface tension supports the spring.

• The spring is made of a special metal.

• The spring is lighter than water.

What role do water molecules play in surface tension?

• They dissolve in the air.

• They bond tightly at the surface.

• They repel each other.

• They evaporate quickly.

How does soap affect the water's surface tension?

• It strengthens the hydrogen bonds.

• It has no effect on the water.

• It makes the water evaporate.

• It breaks the hydrogen bonds.

What happens to the spring when soap is added to the water?

• The spring floats higher.

• The spring sinks.

• The spring dissolves.

• The spring changes color.
