BUBBLE ACTIVITIES
Here are instructions for lots of great activities to enjoy with your bubble kit. You
do not have to do them in this order. Read the instructions for each activity before
you start.
C. MIX YOUR OWN BUBBLE SOLUTION
A bubble solution is included in this kit. However, you need to mix additional bubble
solution for some of the tricks below, such as the mega bubble, the bubble film,
and bubble geometry. You could buy bulk bubble solution from a toy store or follow
the recipes below to mix your own bubble solution. As a quick start, you can simply
dilute dish-washing detergent to make a basic solution. But if you want to make
large bubbles and bubble films, you will need to mix a better bubble solution.
Making your own bubble solution is fun. Here are two recipes which produce good-
quality bubble solution. For both recipes you need a good-quality dish-washing
detergent. These have different names in different countries (e.g. Joy, Fairy, Ivory,
Morning Fresh and Fairy Dawn). They also often come in different strengths: standard
and ultra. Tap water is okay for making bubble solution, but distilled water is better
if you can get it. You will need a measuring jug and a spoon to prepare the mixture.
MIXTURE 1
Materials required: standard or ultra dish-washing detergent, sugar, glycerin
(available from your local pharmacy, this is optional), a container for mixing.
Put 200 ml (6.7 fl oz) of warm water into a measuring jug. Stir in a tablespoon of
sugar until the sugar has dissolved. Add 50 ml (1.5 fl.oz) of standard dish-washing
liquid or 30 ml (1 fl.oz) of ultra dish-washing detergent to the water. Stir in a
tablespoon of glycerin, if you have some. Finally, add 300ml (10 fl.oz) of water into
the mixture and stir well.

What is a bubble?
A bubble is film (a thin layer) of
soapy water that contains air. The
skin is stretchy, which is why you
can blow up a bubble. As you blow,
the skin stretches. It’s similar to
how the skin of a balloon stretches
as you blow it up.
You can often see bands and swirls
of colour in a bubble. They happen
because light rays bounce off the
outside and inside walls of the bubble.
The rays combine or cancel each other
out to make rays of different colours.
Scientists call this effect interference.
The colours change as the bubble’s
skin gets thinner.
Why are bubbles coloured?
