I’ve seen this experiment a few times on Pinterest – and I’ve been desperate to give it a try! 🙂

What do you need?
Blown out egg shells (1 egg makes 2 geodes)
White school glue / glue sticks
Alum
Hot water (almost boiling)
Food colouring (stronger the better) or egg dye

Step 1 :
Cut egg shells in half with scissors, then paint the inside of the shells, and over any cracks, with the glue..

Step 4 :
Stir in 3/4 cup alum, and keep stirring until completely dissolved (if it is not totally dissolved the alum will not be attracted to the egg so much)…
