Bubble Tester for Better Bubbles!

Bubble Testing solutions!

 

Kids love bubbles so this gave them bubbles but also an opportunity to problem solve.  They will test out different solutions to discover which solution makes the best, biggest and most magnificent bubbles!  All  you need is a few items:

  • 4 small containers – baby food jars, bowls, cups…
  • 4 pipe cleaners (just bend into shape) or bubble wands
  • 1 cup measuring cup
  • liquid detergent (Joy and Dawn brands work well)
  • Granulated sugar or corn syrup
  • dropper or pipette
  • Glycerin (available at most drug stores)
  • Optional: watch with second hand
  • Optional: cookie tray

I would recommend doing this activity outside and remind children blow away from anyone.

I took a few minutes prior to doing the activity to add 1/4 cup of water in all of the containers.  In 3 containers I put a squirt of liquid detergent (about 1 teaspoon) and labels those 3 containers with different colored taped to help differentiate the solutions.

I had my students help with the rest.  In the containers with tape, add a 1/4 teaspoon of sugar.  In the last container, add 10 drops of glycerin.

So you’ll have 4 containers:

  1. with only water
  2. with water and detergent
  3. with water, detergent and sugar
  4. with water, detergent and glycerin

Add a bubble wand to each container and stir.  Have your children blow the bubbles and watch the results.  How long did each one last? What colors did they make?  What did it look like right before it popped?  Have your child record their results on their sheets.

Using the cookie tray with a little water, you can blow a bubble on the surface and be able to observe the results longer.

Which bubbles made the longest lasting bubbles?
