NATIONAL GEOGRAPHIC Mega Crystal Growing Kit for Kids- Grow 6 Crystals with Light-Up Stand, Science Gifts for Kids 8-12, Crystal Making Experiment, Science Kit for Girls and Boys

Quite expensive but the effect is brilliant and my 5 year old grandson loves it. It's a good introduction to the wonders of chemistry and crystals. As far as I'm concerned it's perfectly suitable for children under 8 with proper supervision. I think National Geographic just wants to avoid any liability. All the crystals are made using the same chemical compound but with different colouring materials.

Super impressed with this company - we watched videos online of what to do and the instructions we read said to remove the seed rocks after growing. Although we did this super carefully, they all broke into lots of pieces. I wrote to the company and explained what had happened and they very quickly popped a new one in the post for us - the new ones have clear seed rocks so you don't have to remove them. With great customer service I would definitely buy from this company again!!!! The new crystals we grew are very cool - they all turn out slightly differently, but that is the nature of the product and experiments in general!! Great buy - the kids (and us adults!) really enjoyed them!

This is a great little kit and all the crystal turned out like the picture! My son loved this kit and they grew really quick. Tip: use freshly boiled mineral water and place the sachet in the water whilst still really hot. The bigger crystals from our kit grew this way. Each one only took 7 days to grow. In all a great kit to spark the love of chemistry and easy to use. The display base is a bonus too.

There are some good crystals in the set in a range of colours. The light-up stand is an absolutely excellent addition. The information booklet that comes with the product is also of great quality, and clearly a lot of thought has gone into the information in and the presentation of the booklet. If you are looking to make crystals as a STEM activity, this seems to me to be the superior choice.

Wasn't sure which crystal kit to buy for my 8 year old, who has a current interest in crystals and rocks. I am glad we bought this one, as he now has a crystal nightlight in his bedroom which he loves to bits, so it has not been shoved in a drawer somewhere. He and his Dad found the instructions easy to follow, and everything was included in the kit apart from the measuring jug and boiling water! With this kit you get flexible growing pots to grow the crystals in, which you don't get with most other kits. This makes sure they form to a shape that fits in the nightlight stand. There are 2 pots in the box so you can grow 2 crystals at a time. Ours took about a week to get to a decent size, and we discovered if you put a hairdryer on them when you first put them in the pots they do grow faster as they need some heat. I don't know if these would grow faster in summer time or you could put near a radiator to make them grow faster, but they have to be kept somewhere where they won't get knocked or they will be ruined! The kit included a glow in the dark crystal which is an extra one, I think it's good to have an extra one in case one of the others gets broken. The colours aren't as bright as in the picture but they look great in the nightlight and it's nice that in can be used when it's all completed! Would recommend it.

Have only done Two crystals so far but absolutely love them!

This kit was is good I bought several to send to my son's school so that all the children could have fun and learn. The plastic display lamp is a little pointless. Top Mark's

Great kit, kids delighted with it.

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.

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..

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