Science experiment help. (1 Viewer)

[smushieex]

I'm doing this science experiment for school. I'm testing whether various liquids will dissolve the shell of an egg. The liquids being vinegar, coke etc. The only thing is, I have no idea how I'll measure and record the results so that I can put it into an appropriate table and graph.
=SS.
help?

Start with 100mL of each liquid and see how much is left.
e.g Egg disolved in Coke after 3 days there is 90mL of coke left hence 10mL of Coke dissolved in the egg.

Note: You can use any quantity you want.
