I know...I know...
I said that nearly all bubbles are spherical.
Nearly all of them are but not this one.
In this experiment we’ll be making a square bubble!
STEP1 - First thing is to make our square bubble maker. Take a pipe cleaner and bend and twist it round to make a ‘corner shape’ as shown.
WARNING: Make sure that you don’t make your square bubble maker too big, make sure it can fit in your bucket!
STEP2 - Get an adult to help out chopping all of your straws in half.
STEP3 - Slide your ‘half straws’ over your pipe cleaner ‘corner shape’ to make one corner of your cube.
STEP4 - Repeat this process to build out your straw cube framework.
STEP5 - Submerge your bubbler-maker into your bubble mixture. Lift it out and give it a little shake and you should see a wondrous site, a square bubble!
Doesn’t look like it’s possible, does it?
Looks sort of mystical and out of this world but it’s actually all to do with pressure.
A bubble film forms between each of the sides of the cube framework.
This means that you can have a square bubble in the centre where the pressure is close enough to equal to make it work.
