It’s the most wonderful time of the year and you know what that means- time to bring out all of your winter gear and bundle up. But dropping temperatures can also make room for some cool science experiments, like making frozen bubbles! This activity should work if it is 32 degrees Fahrenheit or lower outside with low wind speeds.

  Materials for deluxe homemade bubble solution:

  • 1/2 cup of soap powder
  • 1/2 cup of sugar (the stickiness of sugar makes the bubbles stick and last longer)
  • 3 cups of hot water
  • Bowl
  • Spoon or whisk
  • Bubble wand

Procedure:

  1. Mix the sugar and hot water until all of the sugar dissolves.
  2. Add the soap powder to the mixture and stir. 
  3. Pour the bubble solution into a bowl and take it outside with a wand.
  4. Blow a bubble and catch it on the wand.
  5. Watch the bubble as it sits on the wand in the cold air. The bubble will soon freeze into a fragile crystal ball!
  6. If it is not cold enough outside for your frozen bubble to form, dip a straw in the bubble solution and drag the straw over to a plate. Blow the bubble slightly above the surface of the plate. It will be shaped like a dome. Place the plate into the freezer for about an hour or until the bubble freezes. 

The water in the bubble solution freezes into crystals, appearing on the surface and inside the bubble solution. Study the photo carefully until you begin to see a crystal pattern on the outside of the bubble. Crystals are a special type of solid material where molecules fit in a repeated pattern, creating many kinds of unique shapes. They form in nature when liquids cool and begin to harden. A common example of a crystal is a snowflake. Be sure to visit NYSCI this winter to learn more about crystals!

    Because you’re never too old to blow bubbles.
