Bubble Hoops

Move soapy rings through the air to form bubbles of different shapes and sizes. Experiment using hoops of various diameters and move them in different directions to see how bubbles interact. Observe fluid surface tension and use trial and error to create the largest or longest lasting bubbles. Attraction between water molecules creates surface tension, leading to the bubbles’ spherical shape. Light reflects and refracts through the soapy film to create a vibrant rainbow of colors.
