Last week, students in Ms. Costa’s 11-12 grade class participated in a science experiment about tooth enamel. Students put an egg in various liquids (milk, Coke, vinegar, and Sunny Delight). After 7 days, the students removed the eggs to see what effect the liquids had on their shells, much like the effects they would have on human teeth.

Most interesting was the vinegar egg. The vinegar stripped off the shell and the remainder of the egg bounced!
