Water Is Not Watering? Understanding Hydrophobic Substances and How to Make Them Easily

Have you ever noticed how water rolls off a raincoat or beads up on leaves? That’s because of a hydrophobic surface—a material that repels water. "Hydro" means water, and "phobic" means fear, so hydrophobic substances don’t let water stick to them.

What Is a Hydrophobic Substance?

Hydrophobic materials, like oil, repel water and cause it to bead up or slide off. This happens because they don’t form strong bonds with water molecules.

Simple DIY: Make a Hydrophobic Surface

Want to try making one yourself? Here’s an easy method:

Materials Needed:

• Candle (or paraffin wax)

• Lighter/matches
• Cotton cloth

Steps:

1. Melt the Wax: Light the candle and melt a small amount of wax.
2. Apply to Cloth: Rub the melted wax on the surface of the cloth.
3. Heat the Cloth: Warm the cloth near a flame to help the wax bond.
4. Test It: Drop water on the cloth and watch it roll off!

Where Are Hydrophobic Surfaces Used?

• Rain jackets and windshields stay dry because of hydrophobic coatings.
• Shoes and fabrics resist water and stains.
• Electronics like phones use hydrophobic coatings for protection from moisture.

Why It Matters

Hydrophobic surfaces make life easier—keeping your clothes dry, your electronics safe, and your visibility clear during rain. Plus, you can make these water-repellent surfaces at home with just a candle!
