I found the activity really exciting and challenging becauce...
Challenging: this activity was challening with pulling the insides of the eggs out other wise they will go mouldy. This was hard if you don't have long nails. (make sure you don't crack the egg, does not work)
Exciting: This is exciting because you don't know what is going to happen.
I think that the Blue and Red ones did not work so well because they were cracked and the liqid leacked out.
This is the website that I got instructions off:
