How to Make Magic Sand for a Science Project

Magic sand, also known as aqua sand, remains dry when placed in water. It is essentially sand that has been coated with a hydrophobic substance. Hydrophobic substances repel water, keeping the sand dry. Use magic sand to explain the concepts of hydrophobia and hydrophilia to a group of students or simply use it to encourage them to experiment and observe.

  1. 1

    Cover the interior of a shallow box with a large piece of newspaper, making sure that the bottom of the box is entirely covered.

  2. 2

    Spread a thin layer of fine sand in the shallow box.

  3. 3

    Spray the layer of sand with a thick coating of silicone spray. Scotchgard protector, which is used to protect fabric, is one example of a suitable silicone spray.

  4. 4

    Shake the box to cover the sand thoroughly with silicone.

  5. 5

    Repeat Steps 3 and 4.

  6. 6

    Allow the sand to sit overnight.

  7. 7

    Test the sand by picking up a handful and dunking it in water. If the sand is properly waterproofed, it will remain in a clump in your hand. If it starts to dissipate, repeat the process of spraying it and allowing it to dry.

Tips and warnings

  • Reuse magic sand by pouring it on paper towels to dry and then storing it in small resealable bags.
