Yes, Dino totally destroyed our telephones because they didn't work anymore and we got new ones!!! He had so much fun learning how cordless telephones are made and at the very end smashing them with a hammer just for the heck of it!
Even his Dad joined in helping to take them apart using screwdrivers and pliers and other tools.
Dino enjoyed this activity for almost two hours and I think this was a great experience for him. I hope to find some more things around the house that he can take apart and experiment with in the future.
