We completed our experiment on Friday and recorded our final observations. We found that the egg sitting in water did not change at all in 3 days. However, the egg sitting in vinegar changed a lot. The shell disappeared! We determined that the acid in the vinegar ate away the shell. Everyone got a chance to touch and hold the eggs. The vinegar egg was squishy - many students described it as feeling like a water balloon.
