This was my first time making this type of egg, I think they turned out great. I thought I would share how we made them.
Last night I boiled regular eggs and then we cracked the shells with lost of small crack, before putting the eggs in water with food colouring overnight. LM liked pouring the water into the cups and adding the food colour. She didn't make any mess, but I manage to turn my finger blue while opening a new food colour.
Popped these in the fridge overnight. Took them out this morning and the shells looked quite pretty. LM and I peeled them all to reveal the dinosaur eggs.
