The balancing can experiment

On Sublime Science they have lots of cool and easy to do experiments which are explained scientifically too. Yesterday I had a go at trying to balance a coke can.  This little experiment can be done in about 30 seconds and all you need is a can of fizzy drink! We all know that fizzy drinks aren’t great for us but we can at least do a quick experiment to learn about why things balance!

What do you need: 

  • Just a can of fizzy drink

How do I do it?

STEP 1 – Good news! The very first step is to open up your can and start drinking! Don’t drink it all though…

STEP 2 – Once you’re down to about one third of your can remaining you’ll be able to turn the can onto its side and balance it as shown.

STEP 4 – Take a picture and send it to liam.wanless@parkside.herts.sch.uk

Have a think and discussion with an adult or an older sibling about why the can is balancing before looking at https://www.sublimescience.com/free-science-experiments/balancing-can-experiment/ to see the scientific explanation.
