NATIONAL GEOGRAPHIC Mega Crystal Growing Kit for Kids- Grow 8 Crystals with Light-Up Stand, Science Gifts for Kids 8-12, Crystal Making Experiment, Science Kit for Girls and Boys

These really work! Finally a gem growing kit that forms hard crystals and is fun to watch. My grandson loved the light up stand it comes with and displays the crystals once they’ve dried. They took a week to grow, but the result is durable colorful crystals to keep on his dresser.

The product is amazing! You can create various types of crystals with your children. It's very exciting as the crystals grow. Crystal growth takes 3 to 7 days for best results.

Easy to grow some crystal at home with the kid. Heat some water, dump some powder in, then let water cool, then dump a growing rock thing in the cup. Let sit a couple days and POW/WOW its done. Taking them out and digging the growing rock thing out was a no go. These things are like fine china that break just by breathing on them almost. no lie in my pictures I show they didn't get huge but about the size of the bottom of the growing cup. the tall tower crystals break off so easy and I really hoped that they would dry harder but NO they are still delicate little crystals made only to look at and not touch. at least the plastic LED light base is cool. I plugged mine in to a usb hub in the corner of my kids room to act as a night light. they reflect off the mirror and really brighten up the corner. I do worry that my jerk of a cat might tap them one day and bust them all to hell. good news is that you can just buy a cheep pack of powder and seed growee rock from any random store and use the cool cup to do another batch of crystals. I'll prolly end up buying another one once this one burns out or breaks.

This was very nice ,great for young kids

This was more pricey than what I normally spend on a 'toy' so I was hoping that my splurge would not be in vain. It was given to my 8 year old daughter for Christmas and she was excited when she saw it. The instructions were clear and the growing cups were of good quality. We left the crystals in for 11 days (it recommends 4-10 days) and they were very developed and beautiful once we took them out! The colors of the crystals were not as vibrant as in the pictures though. They were very lightly colored, only slightly more than white. The "seed" rocks (what the crystal grows on) were very difficult to remove and even though I was as careful as possible, the yellow crystal dissolved and broke apart in my hand while I was trying to extract the seed rock. (The seed rocks only need to be removed if you want to display the crystals on the lighted base so that they can light up from the LED's underneath them, otherwise the seed rocks can be left in the crystals). I like that the kit came with more crystals to grow than there are spaces on the lighted base (I think there are 7-8 different colors?) because it gives my daughter options of which she wants to display and change around and you know we girls like changing things around :) Because of the expense this is probably a one-time buy.

This was a gift for my 9 year old for Christmas. He liked it, easy to do and the crystals mostly did great. Out of the 6 , only 1 didn't grow very well. Unsure why. Be aware the light up device only holds 5 crystals, not 6. The instruction booklet is outdated. It sent you to a video link that doesn't work, but it's easy enough to youtube "national geographic crystal growing". Another point is that the video instructions conflicted with the booklet. One said "grow in the dark".. the other said "grow in the light/warm room".. In the end we did half the batch like the video and the other half like the booklet. It was a great learning experience in experimenting and teaching my son to observe which was 'better'. The box also contained just 2 plastic containers.. but we used glass cups from our kitchen since you have to wait 7+ days. We experimented which did better in the soft plastic container v.s. glass cup..

kid thought it was awsome and i had fun doing it s well

Bought for a 7-year-old as a Christmas gift. He loved it continues to play with it as it grows and as he grows. I believe it was worth the money.

Crecen cristales hermosos

This set was awesome and both kids thoroughly enjoyed it! Silicone cups make it easy to get the crystals out. Recommend leaving them in for 7-8 days.

Ho acquistato questo kit per i miei due bambini appassionati di pietre e minerali e regalato a Natale. Finora l'esperienza è stata davvero positiva! All'interno della scatola c'è tutto l'occorrente per creare i cristalli, oltre a 6 pietre. I miei bambini hanno apprezzato queste pietre, anche se senza troppo entusiasmo: da un lato perché hanno già una loro collezione di pietre e cristalli, dall’altro perché non viene spiegato di che tipo di pietre si tratti. Il kit è consigliato dagli 8 anni in su, ma con la supervisione dei genitori è adatto anche per bambini più piccoli (i miei hanno 7 e 5 anni). Noi adulti ci occupiamo della preparazione principale e loro ci aiutano a mescolare; un bambino più grande potrebbe invece gestire tutto in autonomia. La presenza del supporto con luce per esporre i cristalli è un'idea carina, anche se contiene solo 5 cristalli, mentre il kit permette di produrne 6 e quindi uno non viene esposto. Abbiamo deciso di crearne due alla volta, dato che i contenitori inclusi sono 2. Questi contenitori sono morbidi, il che li rende perfetti per estrarre i cristalli una volta completati. Il processo richiede pazienza per i piccoli: dopo la preparazione, i cristalli devono "maturare" per 4-5 giorni (meglio una settimana). Per ora noi abbiamo completato due cristalli e altri due sono in fase di crescita, ma siamo entusiasti del risultato! Un kit creativo e divertente che consiglio a chiunque voglia avvicinare i più piccoli al mondo della scienza e dei minerali.

There is only 7 bags of crystal growing powder, the pink is missing There is only one growing chamber There is no power adapter There is no stir stick And the box was not in a good condition

Es súper divertido y sorprendente como se crean los cristales, a mi hijo le encanto
