Bubble Snake Experiment

Summer is here! 

Kids love bubbles.

It’s one of their favorite summer activities.

Playing with bubbles using a simple wand is fun, but here is another cool way to blow bubbles.

They are called bubble snakes.

Bubble snakes are easy to make and provide tons of outdoor entertainment.

Bubble Snake Experiment

Prep Time: 30 minutes
Active Time: 1 hour
Total Time: 1 hour 30 minutes

Bubble Snake is a great summer outdoor activity.

Materials

  • empty water bottle
  • a small towel or an old sock
  • liquid soap
  • water
  • rubberband
  • scissors
  • glycerin (optional)

Tools

  • adult supervision

Instructions

towel, rubber band, cut up plastic bottle, scissor

  1. Using a pair of scissors, cut off the bottom of the water bottle.
  2. Cover the bottle's bottom with a small towel and secure it using a rubber band. Now you have a bubble snake maker. towel cover the cut bottom of the plastic bottle using a rubber band. bottle neck can be seen from underneath the towel
  3. Next, make the bubble solution. Mix one big squeeze of the liquid soap with one cup of water.
  4. Dip the wrapped end of the bottle into the bubble solution and then blow bubbles through the opening on the other end.

Notes

  • Try mixing food colorings with the bubble solution to make a rainbow bubble snake.
  • Try using different amount of liquid soap and see how that affects the bubbles.
  • Add a few drops of glycerin and see what happens.

Why

Soap molecules have two polar ends — one end likes to stick to water molecules (hydrophilic) and the other end repels water molecules (hydrophobic).

When you mix soap with water, the soap molecules surround the water molecules using the “water-liking” end. So the surface of a soap bubble is actually a thin layer of water molecules sandwiched between the soap molecules.

When air is blown into the soap solution, the air gets trapped under the surface of the flexible soap skin, stretching it into a sphere shape and making a bubble.

No matter what shape the bubble wand is, the bubbles will always be spheres in shape.

That is because a sphere requires the least amount of soap skin to enclose a set amount of air.
