We left our eggs in the liquids over the weekend and observed what had happened on Monday afternoon. Finchley class had great fun discovering that coke stained the egg brown, cracked the egg and the shell was softer. The egg in orange juice cracked, was stained yellow and the surface of the egg was bumpy. The egg in water stayed the same.
The conclusion from our class experiment was that drinks containing sugar damage the enamel on our teeth.
