Bubble Recipes

Ever wonder why Science World’s bubbles are thicker, bouncier and more amazing than the rest? It isn’t a secret; it’s science! Check out our very own bubble recipes.

All-Purpose Bubble Solution

This solution is great for most bubble tricks, activities, and experiments. Johnson’s Baby Shampoo produces much better bubbles than any of the dish detergents we tried. Mix the ingredients gently and let the solution stand for a couple of hours.

Ingredients:

  • 1 part water to 1 part Johnson’s Baby Shampoo
  • glycerine*
     

Bouncy Bubble Solution

You can bounce these bubbles off your clothes! Dissolve the gelatin in the hot water. Add the shampoo and glycerine. Stir gently. This solution will gel as it cools. Reheat it carefully in the microwave (about two minutes).

Ingredients:

  • 1 package unflavoured gelatin (e.g. Knox brand)
  • 250 ml (1 cup) hot water (just boiled)
  • 50–70 ml glycerine*
  • 250 ml Johnson’s Baby Shampoo
     

Thick Bubble Solution

This goopy solution makes bubbles strong enough to withstand a puff of air. When you make a bubble with this solution, try puffing at it to make a bubble inside a bubble.

Ingredients:

  • 2.5 to 3 parts Johnson’s baby shampoo to 1 part water
  • glycerine
     

What does the glycerine do?

Glycerine helps soap bubbles hold water, so that they last longer. It’s very helpful if you’re doing bubble tricks, but less important if you’re mixing up a bucket of bubble solution for preschoolers to mess about with. Most pharmacies carry glycerine. You’ll only need a small bottle—try 1–3 teaspoons for about a litre of bubble solution.
