Egg Science Experiment?
Ok this one defers from the normal one just a little. We have 2 eggs and have to differentiate the hard boiled from the raw one by using the Salt water floatation experiment.
1) drop both eggs into the beaker of water
2) slowly dissolve salt into the water until one of them floats
3) guess which one is the hardboiled one based on the results
The one that floated was actually the hardboiled one and we can't figure out why. Is a solid egg less dense than a liquid egg? Or is the result not based on density at all?

An object only floats if it is less dense than the fluid it is in. Therefore the hard boiled egg must be less dense. When you think about what happens when an egg becomes hard boiled it actually makes sense. When it solidifies it is expanded which means it is taking up more space even though the mass is the same. That would mean that it is less dense than it was before.
