Lab activity for kids.
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.

Fun , easy, educational. Don't recommend for too young kids who don't have patience.
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 The instruction booklet is outdated.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..

Fun kit to do on a stormy day
Got this kit for my son last christmas, we have finished growing all the crystals. Such a fun activity to do with your kiddo on a rainy day. Kit came with everything we needed and the instructions were easy to follow. Loved using this kit because it also leaves your kid with somthinf they can keep. My son is 10 years old and he was able to do most of it himself!

Perfect project for my granddaughter and I
My granddaughter Ellie and I loved making these crystals and waiting the week gave her a schedule where she had to check him every day to make sure they were growing so she had a sense of responsibility that she was helping him grow by checking in on him she's only three and a half but she's learning responsibility already the crystals came out beautiful

Fun scientific experiment!!! But use ALL OF THE POWDER!!!
So I need to revise my review. At first I was very pleased with this “Mega crystal growing lab” until we bought another National Geographic crystal growing lab. The new kit only has 3 crystals to grow in it and a sleaker lighted base but what bothered me was the differences in the instruction book and the difference in the seed rock. In the kit that I am reviewing the instructions say after boiling a cup of water to pour a small amount of the crystal growing powder into the hot water and stir it with the starring stick until it dissolves, then pour in a little more powder and keep stirring, continue pouring and stirring until no more powder will dissolve into the solution. This process should take no more than five minutes Then it says to carefully pour the crystal growing solution into your crystal growing chamber, then let the solution cool for 15 minutes and then place in the seed rock and to leave the experiment undisturbed for 7 to 10 days while the Crystal grows. We followed these instructions to a T. Now the new set with only three crystals in it, the instructions say to pour ALL of your crystal growing powder into the growing chamber and then pour the cup of boiling water into the crystal growing chamber and to stir for two minutes until it is fully dissolved then let cool for 10 minutes And carefully place the seed rock into the solution and it says to let it sit for 3 to 4 days but for best results, let it grow for seven days. We did this two days ago. It hasn’t even been a full 48 hours and the crystals are already bigger in two days than the ones we made from this kit following this kit instructions that we let sit for a week and a half. We only made four crystals out of this set that I’m reviewing but two of those four we could not pull the seed rock away from the crystal for the light of the base to shine up through the crystal so I’m having to take a Dremel tool and try to drill it out so the light will shine through it. As I said earlier, the seed rocks from this other national geographic set were different. They were kind of smooth, so I’m thinking that they’ll pop out easier but the two that I was able to remove from this set one of them removed fine but the second one the crystal actually broke while removing it and then like I said two more I couldn’t even get to remove so I will post pictures of what I have right now and then in a few days once these other crystals are finished growing. I will update my review again to let you know if those seed rocks came out easier, and I will also share pictures of both instruction guides, but if you are going to buy this kit, I suggest going by the instructions that say to dump all of the Crystal powder in at once because doing it a little bit at a time in a little bit at a time the water cools off and you can’t dissolve as much Crystal powder so your crystals don’t grow as big. I still think it’s a great experiment to do with your kids. I just wish that the instructions were the same as in the other set so we would’ve got a better result. Also I wanted to add that it truly is just the difference in the instructions that made the difference because the red crystal and the glow in the dark crystal that we are growing now came out of the mega crystal growing lab set. Only the crystal powder for the blue crystal came from the new set. So use the instructions pictured here that say use all the crystal powder! My 5 year old son and I had so much fun making these crystals. It’s a good value and easy to use and clean up was a breeze. The hardest part was finding a place in my home to set it where it would be undisturbed while the crystal grew. But when it was finished we had big beautiful crystals! I love the lighted stand to display your crystals on but you have to be super careful removing the crystal from the silicone growing container or you will break shards off of your crystals. Totally worth the money! We still have a few more to grow. I personally can’t wait to do the glow in the dark one!

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.

This was a gift for our granddaughters 10th birthday. She has become very interested in crystals, gems etc. We face timed her opening her pressie as they live some distance away. Seeing the wonderment and squeal of happiness when she realised what it was was priceless. She is now busy making her magic crystals with our daughters (her mum’s) help. The first crystal I’ve been told is fantastic so we can’t wait to hear more. A terrific present. Thanks National Geographic!

Mi hija de 8 años quiso este pack para hacer sus cristales, la ayude con la preparación, es muy simple pero obviamente necesitan ayuda. hice como mencionaron en algún Tip que leí, luego de prepararlo lo dejamos en un lugar iluminado y lo tapamos por 24 horas, luego destapado unos días y a los 7 días lo volvimos a semi tapar con una bolsa trasparente. Posterior lo destapamos nuevamente y se evaporo mucho más el agua, donde vivo creo y por lo que lei en las instrucciones funcionó así porque hace mucho calor y humedad, mas durante el día casi siempre estaba el aire acondicionado encendido. Esperamos en total 18 días, el resultado es alucinante y para mis hijos lo máximo. Ahora que vemos funcionó haremos otro. Todo llego a tiempo y funcionando.
