Author: S. RickardRating: 5 out of 5 starsGreat learning experience for the kids. We had a lot of fun watching the crystals grow.
Author: Dave SchoneweisRating: 4 out of 5 starsMy 13 year old was very interested and excited with this gift. I think the age of 12 and older is good. Even so I would recommend adult supervision. It does take quite a bit of effort and extra equipment to set up and perform. It is definitely not an instant gratification type of gift. The first experiment takes a week to see the results.
Author: MichelleRating: 3 out of 5 starsvery detailed instructions, need a big space and lots of items to do these experiments, results are ok but not as shown on box.
