  Clock problems
Posted on: Jan 9 2014 by: 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.

It really works. Tried with lemons and apples worked both times. Took it to school made experiment there as well.

  Fantastic science project!

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!
