How to make "Magic Sand"?

"Magic Sand," also known as hydrophobic sand, is a fascinating substance that repels water, making it look dry even when submerged. Here's how to make it at home:

Materials Needed:

• Clean, dry sand (play sand works well)
• Water-repellent spray (silicone-based or fabric protector like Scotchgard)
• Baking tray or shallow pan
• Aluminum foil or parchment paper (optional, for lining the tray)
• Gloves and a well-ventilated area for safety

Instructions:

1. Prepare the Sand:

   • Spread a thin layer of clean, dry sand evenly across a baking tray or shallow pan.
   • Ensure the sand is free from debris or moisture.

2. Apply the Water-Repellent Spray:

   • Shake the water-repellent spray can as per the instructions.
   • Evenly spray the sand with a thin coat of the water-repellent spray while wearing gloves.
   • Stir the sand with a stick or spoon to ensure all grains are coated.
   • Apply additional coats for better water-repelling properties, stirring between each application.

3. Dry the Sand:

   • Let the sprayed sand air-dry completely for several hours or overnight.
   • Alternatively, place the tray in a warm, dry area to speed up the drying process.

4. Test Your Magic Sand:

   • Place the treated sand in a bowl of water and observe how it repels water and stays dry.
   • You can pour the water off, and the sand will remain loose and dry.

Tips:

• Safety: Use the spray in a well-ventilated area or outdoors. Avoid inhaling fumes.
• Experimentation: Try different types of sand or sprays to observe variations in the results.
• Storage: Keep your Magic Sand in a sealed container to maintain its water-repellent properties.
