How to make a bubble snake

Bubble snakes are super easy to make and great fun for kids of all ages. Younger children will enjoy blowing lots of bubbles easily, while older children can design their own bubbles snakes and even create an investigation using them.

Bubbel Snake

What you need:

Small tube or plastic bottle

Elastic band

Bubble mix – shop bought or make your own

Old cloth for the end

Sharp scissors or pen knife


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.

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

Remember to blow down the bottle NOT suck!!

Why does this work?

When you blow air through your Bubble Snake, hundreds on tiny bubbles are created. The bubbles stick to each other which gives you a big long snake!

So 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 the light diffraction 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?

Can you find a recipe for the BEST bubble mix?
