Hi I'm going to tell you about how dad and I made this crystal. On Friday I was sick and dad found out about my ice crystal homework, so after we had lunch we went to get some copper sulphate. When we went home we started to make the crystal. It was huge! But afterwards lots of pieces started to fall off and it was tiny! And did I mention that it grew in a week. Well dad made another one and it grew in one night! I was so happy I showed it to class just in case more pieces fell off, and I got to boast about it.
