Bubble Snakes

Create fun bubble and foam makers at home! Make long “snakes” of foam, and have more bubble fun, using a few simple items!

What you will need:

  • Small plastic soda/beverage bottles (Note: Sturdier, thicker plastics will hold up a bit better than the thinnest easy-to-crush water bottles)
  • Scissors to cut plastic
  • Small socks such as kid’s socks from a dollar store
  • Food Coloring
  • One or more: Bowl, pan, or plastic tub – large salad or mixing bowl size
  • Dish soap, such as Dawn
  • Tap water
  • Optional: Food Coloring, Pipe cleaners, other plastic cylindrical items, and white paper.

Note: Can be messy & wet. Food coloring may stain. Consider the location and set-up of your experiment.

Here’s what to do:

  1. Prepare a bowl of water with a few spoonfuls of dish soap added to it.
  2. Cut the bottom off of the soda bottle, leaving the other end as it is.
  3. Pull a sock way up over the cut end of the bottle up the sides so it stays on well.
  4. Dip the sock end of the bottle down into the bowl of soapy water and lift it out of the water, blowing through the drinking end of the bottle to make a long “snake” of bubble foam.

Take it further:

  • How long a bubble “snake” can you make?
  • How does varying the ratio of dish soap to water affect the bubbles?
  • What happens if you use a sock that is less tightly woven?
  • Does it make a difference if the sock is cotton, wool, synthetic, or a blend?
  • What about trying other fabric, tied around the end with a rubber band, like a wash cloth or pantyhose?
  • What happens if you try different widths or lengths of plastic bottles?

Other things to try

In addition to bubble snakes, you can also try blowing bigger bubbles directly through things like a small yogurt cup or small plastic bottle with the end cut off.

You can make bubble wands with long pipe cleaners found at craft stores – Try different shapes on the end of your wand, like circles, squares, or triangles! Or a sphere, a cube, or a pyramid!

To make colored soap bubbles, add a little food coloring or water color paint to the soapy water (protect surfaces and clothing from stains)

To make bubble art, try blowing a bunch of highly colored bubbles, then pressing white paper over the bubbles.
