What could be better than giant soap bubbles on a hot summer day? Scientist Factory’s recipe makes soap bubbles a large as human heads.

Equipment

  • 300 ml water
  • 200 ml dish washing soap
  • 50 ml glycerine
  • A bucket or a plastic container
  • 3 straws

Instructions

  1. Mix all the ingredients in the bucket and stir thoroughly
  2. Combine the straws into a triangle, dip into the soap bubble mix and blow carefully onto the soap membrane inside the triangle. It might take a little while before you get big soap bubbles, so patience is key
  3. Tie a long piece of string to two sticks and dip that in the mixture in order to make even bigger soap bubbles

What you can discuss

The soap bubbles become spherical even though you used a triangle shape to make them. This is because a sphere is the best shape for having as much volume as possible on as small a surface as possible. Beautiful colours appear in the soap bubbles because light is bent when it passes through the bubbles. A soap bubble bursts if something pokes a hole in it or if the water evaporates.
