The first one I can remember is when we left one egg in a jar of coke, and another egg in a jar of mouthwash for a week. We thought that the coke would dissolve the egg shell, and the other egg would be fine. But we were wrong! The mouthwash dissolved the egg shell much quicker!
That was a really really long time ago for me, so I don’t really remember to be honest. Before I started school, I used to love watching TV shows about space though. I remember those.
