4M Crystal Growing Experiment

I bought this 4M 7 Crystal Growing Science Experimental kit for my 12-year-old niece, and it's been a huge hit! The kit is easy to follow, and the crystals turned out beautifully. She's now hooked on science experiments and can't wait to try more. The kit is well-designed, safe, and perfect for young teens. Highly recommend for a fun and educational experience!

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!

I bought this for my little brother and he enjoyed getting to grow his own crystals. They are more like borax crystals. Youre not going to get beautuful large points. Fun for kids and preteens

Donated as Christmas gift

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.

No crystal formation as it was claimed.waited for two weeks.Disappointed

Le encantó a un niño de 12 años y ya están creciendo sus cristales.!

bought this item as a gift. the child like it so much. very good buy, fun and educational

I genuinely enjoy this product—it’s practical, durable, and worth every penny.

Me llego el producto equivocado, lo quería para un regalo y abrí la caja para sacarlo y envolverlo el día del evento y me voy dando cuenta que no es, que coraje!!!
