5N made their own bubble maker using string and a drinking straw then explored different recipes for bubble solution. They tested 4 different bubble solutions – each one made with a different washing up liquid brand, warm water and glycerin. Their task was to find out which washing up liquid made the biggest bubbles.
Fairy was our out and out winner by a long way. The squeals of joy, shouts of wow and laughter made it clear everyone had a great time as well as learning good investigative fair testing skills.
