Who knew something as fun and as simple as blowing soap bubble shapes could also be an easy science project for kids on states of matter? See what shapes and sizes of bubbles your kids can blow while they learn about surface tension.

What You'll Need:

  • Dish-washing liquid
  • Measuring cup and spoon
  • Glycerin
  • Water
  • Large container
  • Dishpan
  • Pipe cleaners
  • Plastic soda pop ring
  • Scissors
  • Stapler
  • Wooden sticks

Step 1: Add 1/2 cup of dish-washing liquid and two teaspoons of glycerin to 1/2 gallon of water in a large container.

Step 2: Mix the materials together, and let them sit overnight.

Step 3: The next day, pour the mixture into a plastic dishpan outdoors.

Step 4: Shape pipe cleaners into circles of different sizes.

Step 5: Cut a circle of plastic from a soda pop ring, and staple it to a wooden stick.

Step 6: Dip these devices into the bubble solution, and gently blow through the circles to make bubbles. Circles of different sizes will make bubbles of different sizes.
