With just a few items you'll have at home you can make your own bubble solution and blow bubbles. Find out how to make a bubble fit inside a bubble and much more...

 


     

What you need

Bubble Solution:

  • Dish washing liquid ½ cup (original is best)

  • Water 1 ½ cups (distilled is best but tap water works too)

  • Sugar 2 tsps (bubbles will form without sugar but they won't last as long)

  • Container with a lid

  • Bubble Wand
     

Bubble Wand:

Use a paper or reusable straw as a Bubble Wand. If you want to get creative you could use, pipe cleaners, wire and kebab sticks to create your own Bubble Wand design.

 
     

Instructions:

1. Pour ½ cup of washing up liquid into your jar

2. Slowly and gently add in 1 ½ cups of water, trying not to make many bubbles in the solution

3. Measure 2 teaspoons of sugar and add it to your mixture

4. Gently stir your mixture with a spoon

5. Grab your wand/straw and go outside and blow bubbles!

 
     
 
     

 


Experiment with Bubbles

What you need

  • Water spray bottle

  • Your homemade bubble solution and a straw

  • Clean table or surface

  • Curiosity


 
     

Un-popable Bubble:

1. Spray your table with water

2. Blow a bubble onto the table

3. If you touch the bubble with your dry finger then it will pop. Try it.

4. Now create a new bubble but this time wet your finger before touching the bubble. Ta Da! The bubble didn't pop.

5. You could also cover pointed objects with water and they won't pop the bubble either.

We covered Feathers McGraw (the toy penguin) with water and placed him inside our bubble. What else could you try?

 
     

 

Why do bubbles pop?

The bubbles ‘skin' is made up of a layer of water molecules sandwiched between two layers of soap molecules. As the water layer is lost from the layers of soap the bubble will pop.

There are different ways that the water may be lost;

1. Evaporation in a warm or sunny environment

2. A rush of air such as wind which breaks the bubbles layers

3. Bubbles also pop when the water molecules are attracted to a dry hand or object (this is why wetting objects helps to keep the bubble intact.)

 

Blow a Bubble inside a Bubble

1. Spray your table with water again

2. Blow a bubble onto the table

3. Dip your recyclable straw into the bubble solution so that the bottom half is covered

4. Poke your straw inside your bubble and blow a new bubble inside the first one

5. See how many bubbles you can fit inside one big bubble


   
     
 
     

Science Note:

When you blow a bubble inside a bubble you might notice that the outer bubble also starts to grow. This is because the outer bubble adjusts its size to fit everything inside including the air it was already filled with.
