Space Sand, just like sand from Mars! - Explore the hydrophobic properties of Space Sand!
This sand has been exposed to the vapors of a silicon compound, which changes the composition of the sand and makes it un-bondable with water - hydrophobic!
Try it for yourself - pour it into water and watch in amazement as it never gets wet. Form it into stalagmite figures, shapes and even letters under water! Use a spoon to remove the sand from the water and watch it magically dry as it comes out! There are many creative uses for Space Sand - it has been used to clean oil spills, improve the growth of plants by providing aeration for the roots, and is even being used in experiments covering the Mars exploration.
What fun and interesting experiments can you conduct using Space Sand?
Here's one to get you started, make a Sand Raft!
- Slowly sprinkle your space sand on top of water
- If you leave small amount on the surface of the water, it will float
- As you add more Space Sand, it will sink, penetrating the surface tension of the water.
