100 Days Project

Nanogirl: Star Science

Nanogirl wants to find 100 friends to do science experiments with her to prove that no matter who you are or what your education level, you can always have fun with science.

Day 54:

Hydrophobic sand

If you take some sand and spray it with scotch guard (which is used to waterproof shoes) you can waterproof your sand!

This makes the sand do strange things when you dip it in water and you can make underwater shapes with the sand!

Hydrophobic means it doesn't like water.
