# Geometric bubble films - make a cube shaped bubble!

### You will need:

• 4x Pipecleaners
• Strong Bubble mix
• Deep bucket
• Somewhere you can get wet!

Cube shaped bubble materials

#### Instructions

1. Pour the bubble mix down the sides of the bucket to avoid making small bubbles.

2. Connect pipe cleaners together to form a cube ... i.e. 6 sides.

a) First fold one of the pipe cleaners into a square.

b) Now fold another of the pipe cleaners into another square and chop one of the other pipe cleaners into 3 parts. Leave one pipe cleaner untouched at this point.

c) Wind each of the short pipe cleaner pieces onto the corners of the 2 squares made.

d) Finish off the cube with the final pipe cleaner and leave a small amount hanging off the cube to act as a handle. You can straighten up the frame later.

3. Dip the cube into the bubble mix and carefully withdraw it a couple of times. Can you make a cube-shaped bubble form on the inside of the pipe cleaner frame?

4. Try making tetrahedron (4 sides), a octahedron (8 sides), and a dodecahedron (12 sides)!

5. Does the bubble shape match the shape of each frame... why?

#### Why Does This Happen?

Bubble films are stretchy... scientists call this 'stretch' surface tension. As bubbles are stretchy, they always try to shrink into a sphere shape, minimising surface area.

Dipping the frame into the bubble mix traps air inside the frame. The bubble inside the frame tries to form a sphere but the bubble films connecting to the frames pull on the bubble on the inside. This creates a bubble with the same shape as the frame.
