Lochie and Jackson decided to do a science experiment to find out. First they put an egg in normal water and it sank to the bottom.
Next they tested it again by adding lots of salt to the cup of water and then trying again but the egg still sank.
They wondered why it hadn't worked so they found the instructions and re-checked their measurements. They worked out they needed to add quite a lot more salt (7 tablespoons) to half a glass and mix it well before adding more water.
This time the egg floated! Success.
Lochie and Jackson left it for a few days to see how long it would float for and it was still floating a few days later!
Why do you think the salt made a difference to whether the egg floated or sank? What is your hypothesis?
