Synthetic science meets slithery nature.

Synthetic science meets slithery nature.

Usually we’re working in our lab (the garage or kitchen), when we undertake a new science, technology, engineering or math experiment, but this time we’re headed outside. Trust us – it’s better this way. Things are going to get delightfully messy. Making a bubble snake is a pretty quick activity that promises tons of fun for kids of all ages. Plus you probably have all the supplies on hand.

We’re engineering our self-powered bubble machine using common household items by incorporating some simple engineering and chemistry methods.

Snake Bubbles

Here’s what you’ll need:

  • Dish soap
  • Food coloring
  • Plastic drinking bottle
  • Rubber band
  • Scissors
  • Spare sock
  • Water

Here’s what you do:

  • Cut off the bottom end of the plastic bottle.
  • Now wrap the sock around the bottom of the plastic bottle.
  • When it’s taut, secure the sock to the bottle using the rubber band.
  • In a mixing bowl, combine about a cup of water with a quarter cup of dish soap.
  • Apply a few drops of food coloring to the bottom of the sock.
  • Dip the sock in the soapy water.
  • Hold the drinking end of the bottle to your mouth, and blow air through the bottle.
  • Watch the snake bubbles come alive!
