The kids began making alum crystals way back in October, but we delayed checking out big they had grown until today after their final. For your reference:

Student response varied:

* WOW!

* My crystal is bigger than yours!

* It looks like Mickey Mouse

* Can I show my teachers?

* Can I sell it?

* So how do you make diamonds?
