- In Activity 2 you were able to float a paper clip on water even though a paper clip is more dense than water because of the surface tension of water. Do you think you can float a needle? What about a square piece of foil? What about a penny? Experiment with floating different objects on water and devise a general rule for what enables you to float an object. Pay attention to size and shape.
- Have you ever seen strange colored carnation flowers for sale? Sometimes these strange colors are made using food coloring. Try dying flowers or a celery stick using capillarity and colored water.
- Devise a way to use capillarity to water plants without overwatering them.
- The “Cheerios effect” can explain why cheerios in a bowl of milk will move towards each other. Investigate how this effect works and what other aspects of science it relates to.
