Easter Eggs?

Some kids dye eggs at Easter. M. experimented with them...

This was after they were in vinegar for two days. I helped rub the shell off (but only because this was his third attempt - the others either burst in the vinegar or while he was rubbing). 2nd liquid: diet coke

3rd liquid: green tea (the 4th was blue salt water)

The project was complete after 6 days. It was all about osmosis and diffusion.

After all the necessary data, the boys had a little fun with the eggs.
