    Good product, tad bit messy
    Crystal instructions were detailed and easy to use. Takes a little time, and some crystals did not grow properly. Growing solution stains hands and countertops, so be sure to use gloves and Clorox wipes. All in all, a good product.

    5.0 out of 5 stars This set is AWESOME! I highly recommend it
    Reviewed in the United States on February 25, 2016
    This set is AWESOME! I highly recommend it! I purchased it to grow crystals in the office as a fun experiment to keep me entertained during busy season and it did not disappoint. You need to be sure to follow the instructions carefully. I made a fatal error on my first attempt and did not wait the full 30 minutes before I added the crystal seeding and nothing ended up growing. On the subsequent attempts I followed the instructions to a T and was able to grow beautiful crystals. I even ordered a second set because the results were astounding.

    The steps are simple enough I was able to grow these in my office with ease. All you need is boiling water and the rest is provided in the kit. The first step is to dissolve the crystal mixture (it looks almost like sugar) into hot water. Next, you have to let it sit for 15 minutes, and then transfer it into a clear plastic container where the crystal will grow. WAIT ANOTHER 30 MINUTES after the water is transferred. This step is crucial otherwise the crystals will not grow.

    Once you have waited the allotted time you drop in the crystal seeds. They provide blue, red, and white crystals so you can mix and match them to create different colored crystals. It seems that each type of crystal seed grows a different shape of crystal. I noticed that the red crystal seeds will grow more block-like crystals whereas the blue seeds will create more sharp/pointy crystals that flower out. Blue and red will create a crystal that looks like a combination between the two - it flowers out but is more block-like. Keep this in mind when you choose the colors you make.

    You will start seeing growth overnight. Its amazing to watch the progress. On the instructions it says it takes 4-7 days before the crystals are fully grown. I would keep an eye on them and drain the water when the crystal is about to emerge from the water. If you leave it too long the crystal is exposed to the air it will form "snow-like" growths on the top (which I think are ugly). The rate of growth will be affected by the temperature of the room as well as the size of the crystal you are growing. The crystals grow well in warmer temperatures. The small crystals will finish growing faster than the large ones.

    Each bag of crystal mixture can either make 1 large one, 2 medium sized one, or 4 small ones. The kit allows you to grow 1 large crystal, 2 medium crystals, and 4 small crystals simultaneously because that is the amount of containers they provide. If you want to grow 3 large ones you can grow them one at a time because they only provide one large container. I think the large crystals are the coolest.All in all this is an amazing kit. Everyone in the office is jealous and now they want to grow their own crystals too. 5 stars!!! I want to make ALL the crystals!

    5.0 out of 5 stars and they all look nice, but the color did not turn out well ...
    Reviewed in the United States on January 3, 2017
    This was a Christmas gift, and so far they have turned out well. We have only completed the 4 small crystals, and they all look nice, but the color did not turn out well on the "purple" crystal. We may not have put enough blue color to balance it correctly. Ours grew for 6 days, however we did see results after 24 hours. They all had the flaky growth on the outside of the cup, which cleans off easily when they are finished growing. We started seeing this around day 3 on the dark blue, and by the end of day 6, it had occurred on all of them. The 2 blue seem to be more delicate than the 2 red.

    Some people said they followed the directions to a T, and did not see results. One thought is perhaps the temperature of the room where they were growing them is not warm enough. I believe the directions say to make sure the room is above 68 degrees. We grew these in our basement, and I made sure to turn up the heat to 70 while these were growing. If you follow the directions, keeping in mind the temperature, I don't see how it can't work. One last thing...it definitely requires adult supervision (really they have to do all of the work), I would say up to at least 12, due to the boiling water and chemicals. We will finish these out as is, but I would buy it again, and make 3 large crystals, or all medium. I wouldn't bother with the small crystals.

    4.0 out of 5 stars Fantastic if you used distilled water
    Reviewed in the United States on January 23, 2023
    The crystals came out fantastic when we boiled distilled water rather than tap water.

    For those getting weird formations, you may have sediment or other things in your water that is messing it up. Also, depending on the temperature and humidity in your home, the time it takes for full formation may vary. The first formations took less time than subsequent ones because it was warmer and had less humidity.

    This was a super fun, super easy, way to teach my daughter about crystals and how they form. We'd use a flashlight (being careful not to disturb the solution) and check them out as they were growing. She was particularly interested in the little crystal formations as they crawled up the side of the container like they had a mind of their own.

    Would definitely buy again.
