Science experiment: Making butter

So this little science experiment is edible, which makes it more fun! Problem is, you have to work for it. Shake the jar hard and fast and you shall be rewarded with a delicious version of your own butter.

What you need:

• clean jar
• double cream
• salt

Number of players:
1+

Activity:

Put double cream into a clean jar until it is about half full and then add a pinch of salt.

Shake the jar for fifteen minutes – you may need the help of a friend as it gets very tiring!

You should notice that the double cream and salt is separating into a lump of fat and a milky liquid.

Take the lump out of the jar and put it on a paper towel so that you can wrap the towel around the lump and remove any excess liquid.
 
Taste the lump – it is butter!
