Expert Answer:

There is interesting experimental project about buoyancy and density. Eggs normally sink in tap water. By changing the density of water, you can make the egg float or submerge. This project makes an interesting and exciting display.
 
This project does not take much time and often can be completed in one or two days. You will need some clear jars (or beakers), a few eggs, some salt and some water. Performing the experiment and recording the results takes a few hours. You then need to prepare your display with tables, graphs and charts to explain this phenomena.
