NSI Smithsonian Crystal Growing STEM Science Kit - Age Group 10 Years and up

hope it's a good gift

Good

I bought this for my grandson. It was missing about 1/2 of the products in the box. I don't know if it would be a good product or not based on the price. I gave it a 1 because we were not able to do the activities.

My son and I have grown several different crystals so this was not our first time growing crystals. I bought this one because we could watch several at a time. We followed the instructions step by step. I believe the instructions are wrong and the larger bag should be mixed with the larger quantity of water, but when following the instructions. The smaller bag is done first so when you get to the second part of the instructions it is to late to do it right. I sent an email to the company explaining the problem and that the chrystals didn't grow. Their response was to re-boil everything and try again. If there was to much water to begin with what is re-boiling going to do?

Very disappointed with kit... Stayed that crystals would start to develop after a few hours and in 4-5 days they would be fulky developed crystals.. 7 days later and rocks are still in solution and nothing...

It had pieces missing.

My daughter really likes science, so she received this as a gift. The first set never grew more than a dime size and highly doubtful the second set will either considering the mix wouldn't dissolve. Very disappointed!!
