2 star rating  Clock problems
Anne from Spring TX
These worked just long enough to see the science behind it, but the clock just didn't keep the time efficiently. This clock is considerably better than the one that comes with the lemon clock, but still not time-telling.

5 star rating  Cool
Nathan from NV
It really works. Tried with lemons and apples worked both times. Took it to school made experiment there as well.

5 star rating  Fantastic science project!
Jody Pike from USA, Akron, OH
Our son absolutely loved building the clock for his 3rd-grade science project. Directions were pretty clear and clock worked like it should have. Definitely recommend this!
