Buoyancy can be really tricky to understand, our easy experiment will help you to understand why some things float and others sink. Plus, you get a treat at the end of it!
You will need:
- A bucket or tub
- Can of pop
- Can of diet pop
- Fill the bucket with water
- Make a prediction, will the can of pop sink or float?
- Drop the can of pop into the water – what happens?
- Make a second prediction, will the can of diet pop sink or float?
- Drop the can of diet pop into the water – what happens this time?
