Water, Salt and Eggs Please!

This morning, 5DC spent time in the MS science lab.  There we wanted to solve the question:  How many tablespoons of salt is needed to float an egg in 200 mL of water.  Armed with a chopstick, an egg, a 200 mL beaker, a spoon, 200 mL of water and a 5 kg bag of salt, we were determined to find an answer.

How many spoons of salt do you think we needed?
