    I've not long had this product so I may have more to add to he review later. Being an overgrown child I bought this for myself and am looking forward to a selection of crystals as displayed on the box. However- if I do manage to grow them it will be no thanks to the instructions as they are diabolical.Ther is no real indication about he amount of salt needed to conduct an experiment or how much to transfer to another container.For a scientific kit I find this unforgivable. They talk about not letting the heat of the surrounding water to rise above 60 degrees c but then use vague terms like 'about hot enough to put you finger in' .The salt in my first attempt never did 'dissolve' at this temperature. What are you meant to do? If the manufacturer ditched some of the rubbishy plastic 'accessories' and instead got someone who knows what they are talking about to rewrite the instructions this might be a good kit.

    A lot of kit for the money. Before you go out and buy one check the age range of the product. Some of the chemical's can be hazardous and in the mixing process you need to heat on a stove. Good fun but slow.

    Got this for my partner for Christmas because he never had one when he was a child and he's really enjoyed making them and I'm sure children would as well.
    It's perfect for either just some fun or some more serious experimentation. Includes everything you need and is great value - much better than the kits that grow overnight on a sheep or something and are only one colour. This kit has loads of colours, but they do take around a week to grow fully. Also comes with a handy display table
    Overall a great buy and very fun

    I have tried this toy with my kids because my mum got it for them. I think this toy is really good, because after about 20 mins small things were foriming at the bottem of the jam jar. Says that it includes everything but you need a jam jar. Still very good. The instructions are a little hard to understand so i think that an adult is recommended to help their child when they do this. Includes lots of experiments.

    Pros: lots of salts in different colours. Cons: not clear that you need a "jam jar" from the outset. This is a hassle and we don't normally just have them lying around. For the price, why not include a small pyrex beaker? Esp if you then want the child to stir it in a water bath over an open flame! Madness. I found it much easier and safer to use boiling or near boiling water from the kettle, as I could control this better esp as the temp required was only 60 deg and we could do this in the garden.

    The instructions I generally thought were poor, and did not include nearly enough useful info, IMO, about the structure of crystals, how and why they grow. Why a seed crystal is helpful. Why do they grow better suspended from a thread? The importance of a saturated solution, etc. Also, not enough explanation of what the petri dishes, etc are for. The diffferent activities were fun useful and varied but could have been better laid out.

    My daughter has this for the past two years and we have tried on at least 3 occasions to make chrystals without success. The salt will not fully melt no matter how long we stir it or how high we heat it. We haver never produced anything like a proper chrystal. very disappointed

    We got this for our son for his birthday and has turned out to be the most frustrating science kit.I found the instructions quite poor which is in my opinion unforgivable for a 'science experiment kit'. This seems to be par for a lot of 'reputable organisation' branded products such as microscopes and telescopes marketed by The Science Museum, National Geographic etc which we have been given - Poor quality products which are usually not fit for purpose. For example, in this crystal making kit, with the basic how to grow crystals instructions, you have vague instructions such as 'stir in the salt until it dissolves and when it has all dissolved.... (no troubleshooting for what to do if the salt hasn't dissolved!) Then in the same paragraph you are told to use the dropper to place drops of the made up solution onto the petri dish - but not how much! This is pretty important stuff as you will be using these crystal seeds for the later activities! I have noticed other reviewers moaning about the fact that the salts don't dissolve. We have exactly the same issue with both types of salt. This means I have no idea whether the solution we are making is correct. The boy is quite simply bored of the kit and I wish we had bought something else.
