Why does soapy water make bubbles?

When soap molecules mix with water molecules, they tend to separate out small bits of water to form bubbles. When soap mixes with water, the opposite ends of the soap molecules sandwich a thin layer of water between themselves. This creates a thin film that encompasses a tiny bit of air.

Besides, why does detergent make bubbles?

Detergent lowers the surface tension of water enough so that bubbles can form. Bubbles burst when the layer of water molecules between the detergent molecules evaporates.

Secondly, why does a soap bubble have two surfaces? Soap bubbles and raindrops are spherical because the sphere is the shape with the smallest surface to volume ratio. The surface tension balances the outward force due to the pressure difference between the inside and the outside air. We have two surfaces, the inner and the outer surface of the bubble.

Then, what ingredient in soap makes bubbles?

The glycerin or corn syrup mixes with the soap to make it thicker. The thicker skin of the glycerin bubbles keeps the water from evaporating as quickly, so they last longer. It also makes them stronger, so you can blow bigger bubbles.

What is the best homemade bubble solution?


  • 6 cups water (distilled is best but tap water is fine)
  • 1/2 cup blue Dawn dish detergent I used “ultra concentrated”, but Dawn original is even better.
  • 1/2 cup corn starch (corn flour in the UK)
  • 1 tbsp baking powder (not baking soda)
  • 1 tbsp Glycerine (or personal lubricant)
