DIY HYDROPHOBIC SAND UNDERWATER EXCAVATION
Hydrophobic sand is a lot of fun to explore and enjoy but it can be a little expensive. In this quick post we are going to show you how to make your own hydrophobic sand for a fraction of the price. We are then going to teach you how to use your homemade hydrophobic sand to create an underwater excavation experience for your little ones to experience and enjoy.
- Colored sand - you can use regular sand too!
- Fabric water repellant
- Paper plate
- Disposable plastic spoons
- Seashells, shark teeth, or other items to hide in the sand to be discovered. You may want to use little plastic ocean animals but just be sure that they sink for this underwater excavation activity.
- Clear container - a clear 9 oz plastic cup works well.
