Soap Bubbles

One can do many things with soap bubbles. In the photograph above, Summer Camp visitors (2007) are making large bubbles using ‘bubble trumpets’. One can make a huge bubble with these devices. There are many ways to make bubbles. The girls are about to try blowing small bubbles inside the big bubbles, using soda straws.

At the BIG Little Science Centre, we make a 4-litre batch of soap bubble mixture using about 350 mL of Blue Dawn, 50 mL of glycerin and 3600 mL of water. Put the water in a 4 L container first, and then add the detergent and glycerin. Let the mixture stand for a day or longer. This mixture can be used to create huge
bubbles outdoors. For best results choose a cool, calm, humid day so that your bubbles last

How to make a Cubic Soap Bubble

A bubble maker the shape of a cube is dipped into a large pail of soapy water. Surprisingly, this creates a double pyramid shape (left photo). Alex Campbell shows what to do next (right photo). If you dip a soda straw in soapy water, then insert it in the middle portion of the double pyramid, and blow air gently into the existing film, you create a beautiful cubic soap bubble. The bubble maker shown in the photographs is available from Steve Spangler1. You might wish to make your own cubic bubble maker using soda straw.
