Use the plastic spoon to stir the sand every few hours until completely dry. Once your hydrophobic sand is dry, fill the clear plastic cup with water. Place a spoonful of your DIY hydrophobic sand into the water and observe. Using the Magic Sand students can develop models to describe the atomic composition of simple molecules and their structures or properties. Students will observe and communicate scientific information about why the molecular-level structure is important in the functioning of a material.
Emphasis is on the repulsive forces and the hydrophobic nature of the Magic Sand. Investigations using the Magic Sand will demonstrate the attraction and repulsion between electric charges at the atomic scale explain the structure, properties, and transformations of matter, as well as the contact forces between material objects.

May 24, Amazingly stays completely dry in water. Very very hard to clean up. Quite impossible to separate from water completely. Except it's even better, because it's science. The experiment is also surprisingly simple to replicate at home.
All you need is some sand and some water-repellant spray, such as Scotchgard or gotchscard, which you'll understand when you see the clip above. You spread the sand out and then give it a couple of genorous coatings of water-repellant chemicals.
Once it's dry, you're now the proud owner of hydrophobic sand. Grab your lab coat. Let's get started Welcome! It seems this is your first time logging in online. Please enter the following information to continue. As an ACS member you automatically get access to this site.

Magic Sand And Kinetic Sand These toys are popular in classrooms and on desktops because of their logic-defying properties by Andrea Widener March 23, A version of this story appeared in Volume 93, Issue Trying To Explain A Bond.
Magic sand has a thin coating of trimethylhydroxysilane, which makes the sand hydrophobic. But when you place it underwater, magic sand starts revealing its unusual characteristics. You might also like Spray-On Particles Waterproof Paper.
