Great gift
My 6 year old absolutely loves it. Instructions are clear and the results are quite impressive. It's a lamp too, which I wasn't expecting and light shines through the crystals.

Recommended science activity
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.

My 8 year old son loved it!
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.

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 is a gift so unable to say if it performed as described, however delivery and expectations have been fully met.

Very nice kit. The light stand is also very nice. It's nice to see the crystals grow. You can do 2 crystals at once, and the kit contains 6. Expect a whole week for the crystals to grow. Kids love them!
