- Pour 350ml water into measuring jug.
- Add 2 teaspoons of sugar.
- Mix until sugar is dissolved.
- Gently add 150ml Fairy Original washing-up liquid.
- Stir gently until completely mixed (your aim is to combine the water and liquid whilst creating the minimum amount of froth- you do not want bubbles yet)
In this way, why does sugar make better bubbles?
This is because the surface tension—the forces holding the molecules of a liquid together—of water is too high. When detergent is added to water, it lowers the surface tension so that bubbles can form. Add other things, such as corn syrup or glycerin, to improve the bubbles.
Do soap bubbles help clean?
Trapped air in pockets doesn't clean. The soap molecules in the water are what's cleaning. Regardless, many commercial and soap manufacturers add chemicals specifically to create bubbles throughout washing, just to satisfy people when they look in their machine.
Why do you need soap to make bubbles?
The soap molecules “surround” the water molecules, with the “water sticky” bits pointed towards the water, and the “water repellent” bits pointed away from the water. This is what the surface of a soap bubble is — a thin layer of water sandwiched between the soap molecules.
