Review: I would recommend this - Quick delivery. My Grandson loves this crystal growing kit.
Review: Great results if environment right - Saved using this until I knew we could have the heating on having read other reviews re poor results. Clear instructions. We put them on a shelf above a radiator to ensure optimal growth and were really pleased with the results. Ended up with spikey and cubed crystals of various sizes which my 7&8 year old boys enjoyed checking each day. Useful info re learning points for kids also included. We think it was worth the money and a lovely project for half term :-)

## Questions & Answers

**Q: are the instructions in english**
A: Hi, Our pack and instructions are both in English, our box says 4M Crystal Growing Experimental Kit on the box, not like the image shown. Mark (Inspiring Toys)

**Q: once fully grown and taken out of the liquid do the crystals remain stable**
A: If you are careful and follow instructions and be patient then you will get some lovely crystals that we have kept for quite some time that are still ok.
You can redissolve crystals and dry out and try again if you fluff it first time around.

**Q: What type of crystals are they?**
A: The crystals are called 'monoammonium phosphate' which are a base compound, it grows into tetragonal crystals.

**Q: Very mixed reviews. Why have some been able to grow crystals and some not ?**
A: I followed the instructions and nothing appeared to be happening and I literally forgot about it until I came back a week or 2 later!! Maybe some are just slower to grow depending on temperature they're in?
