Bubble Snake Instructions

First you need to cut the bottom off your water bottle – ask an adult to help and be careful as the end might be sharp.

Cover the end of the bottle with a piece of cloth and secure tightly with an elastic band.

Dip the cloth end into bubble mix.

Blow carefully down the other end of the bottle and watch as a bubble snake appears!

Remember to blow down the bottle NOT suck!!

Make it an investigation

How does a bubble snake work?

When you blow air through a bubble snake maker, hundreds on tiny bubbles are created. The bubbles stick to each other creating a big, long snake!

Why are bubbles round?

Bubbles consist of a thin film of soapy water filled with air. When you blow a bubble, the film expands outward. The forces acting between the molecules of the bubble cause it to form the shape that encloses the most volume with the least surface area — a sphere.

Why can you see colours in bubbles?

Colours are seen because of light diffracting through the soap film.

How can you make this a science fair project or investigation?

Try using different materials on the end of your bubble snake, can you predict which will make the best bubbles?

Can you find a material that will give you bigger bubbles?

What happens if you blow more slowly?
