This experiment tests whether sugar is heavier than artificial sweeteners
Ingredients and equipment that you will need
A can of fizzy drink
A can of diet fizzy drink, the same type
A large bowl of water – or you can do this in the sink
Method and further information
Fizzy drinks have a lot of sugar in them whereas diet drinks use artificial sweeteners. Artificial sweeteners are lighter than sugar.
Put both cans into a large bowl of water or into the sink.
You should see that the diet one floats better because it is lighter.
Be careful – you should ask an adult to help you with these experiments. Do your experiments in old yoghurt pots, jam jars or bottle tops. Don’t use cups or glasses in case someone thinks it’s a drink.
