Science of Bubbles

Spring and summer is the best time to get students outside exploring nature and having fun in the sun. One of my favorite science investigations to do with kids of all ages is exploring bubbles.

Here’s the science behind the phenomena:

• Soap bubbles are always round because liquid molecules like to stick together on the surface, which causes them to create a round shape.

• The molecules create something called surface tension, which is like a force that keeps the bubble together.

Check out my favorite bubble wand methods:

Pipe Cleaner Bubble Wand

Bend a pipe cleaner into various shapes, including hearts, circles and squares. See how bubbles transform into round shapes. This method is best for younger students.

Straw Bubble Wand

We tried threading a string through two straws. When dipped into bubble solution, the straws can be pulled apart slowly to create a bubble. Blow through the middle of the film.

Dowel Bubble Wand

Create a loop with string by tying the ends together. Attach the string to two dowel rods at different points. Dip the string into bubble solution and pull apart slowly. Walk backward to create a large bubble.

Try this Bubble Craft!

Put a little dish soap, water, and food coloring in a container. Experiment with dropping the food coloring in last or mixing. Lay a piece of paper on top of the bubbles and lift to find bubble designs!
