Magic Sand

The Magic Sand experiment will demonstrate the waterproofing ability of commerically avaliable products. When normal sand is coated with this water proofing spray, it behaves very different to uncoated sand and forms structures under water. Additionally, upon removal of the Magic Sand from the water, it will turn back into a free flowing solid powder! It's magic!

Suggested teaching points

  • Hydrophoic materials
  • Commercial application of chemistry
