This review is from: 4M Green Science Potato Clock (Toy)
I had my doubts about this but also I was more excited than my son to find out if it would really work!
It does! And it lasts a long while too! Not a flash-in-the-pan type of experiment. It also encourages you to try other fruits/vegetables to see if they will work the clock too... This was a clever little experiment and we're slowly working our way through the range... Very happy so far!
