This week, we carried out an experiment, ‘How to make eggs float’. We predicted that different things like sparkling water, vinegar, 7up, salt and oil would make an egg float. We found out that eggs will float in salty water. Objects sink in water when they are more dense than the water. By adding salt, the water became more dense. When the water was denser than the egg, the egg floated.
