Bouncing Bubble

Water, dish soap and glycerin... but what else do you need to make a bubble bounce? No pop bubbles are just a glove away.

With the Bouncing Bubble, that little puff of air trapped in a thin soap film will bounce. What?!?! It’s true! These bubbles are formulated to be stronger than normal, but would still burst if they touched your skin or the ground. The secret is in the Bubble Gloves that keep the floating soap sphere from bursting when it touches your hand.

Experiment

1

Pour 3 parts water and 1 part dish soap into a small cup.

2

Stir to combine. We suggest letting your bubble solution rest for 24 hours for best results. You can also use a small amount of Bouncing Bubble Solution instead of making your own, if you would prefer.

3

Test your solution with your bubble wand. Try holding a bubble in your hand.

4

Put on the glove. Now, blow a bubble. Try holding the bubble and bouncing it.

How Does It Work

A bouncing bubble is amazing because most people have never seen a bubble bounce, much less be the person who actually does the bouncing! Experience shows that bubbles usually burst when they come in contact with just about anything. Why? A bubble’s worst enemies are oil, dirt, and gravity. A “super” bubble will bounce off of a surface if the surface is free of oil or dirt particles that would normally cause a break in the thin soap film of the bubble. The problem with gravity and evaporation is that the water film gets very thin (down to a millionth of an inch) on the top surface as time passes. It finally gets too thin to hold onto itself and the wall collapses completely.

Similar to the way we perceive the colors in a rainbow or an oil slick, we see the colors in a bubble through the reflection and the refraction of light waves off the inner and outer surfaces of the bubble wall. You can’t color a bubble since its wall is only a few millionths of an inch thick. A bubble reflects color from its surroundings.

Take It Further

Want to make your bubble solution even stronger? Read the information below and see if it helps you make an even stronger bubble solution.

Water – The single most important part of the bubble solution is the water. Good quality water that does not contain high levels of iron or minerals is best. If you’re uncertain as to the quality of your tap water, invest in a gallon of distilled water from the grocery store.

Soap – When it comes to soap, Dawn® dish soap just seems to work the best for homemade bubble solutions.

GlycerinGlycerin is the secret additive that gives a bubble its extra strength. Don’t be too shocked by the price on a bottle of high quality glycerin. Contact the pharmacist at your local grocery store for availability. (Note: Some bubble recipes substitute Karo® Syrup for glycerin due to the expense and availability of glycerin.)

When making your new batch of bubble solution, remember to use two parts water and one part soap. Experiment with how much glycerin to add to make the strongest and bounciest bubbles.

Science Fair Connection

Demonstrating properties of bubbles and bouncing them is pretty cool, but it isn’t a science fair project. You can create a science fair project by identifying a variable, or something that changes, in this experiment. Let’s take a look at some of the variable options that might work:

  • Try testing different dish soaps. You can blow bubbles with different brands or try using the same brand, but with different scents! Which dish soap creates the longest lasting bubble?
  • Test different bouncing materials. In addition to the Bubble Gloves, try t-shirts, towels, pants… whatever you would like. Time the bubbles to see how long it takes them to pop!

That’s just a couple of ideas, but you aren’t limited to those! Try coming up with different ideas of variables and give them a try. Remember, you can only change one thing at a time. If you are testing different liquids, make sure that the other factors are remaining the same!
