Original Stationery Dinosaur Crystal Growing Kit - Multicolor, 17-Piece, Ages 7 & Up - DIY Science Terrarium Kit with Moss & Dino Figures - Grow Your Own Crystals - Boys Birthday Gifts

Great gift! Fun idea for kids to do. Not super messy. Bought for a kid 7-10. I would also use this.

amazing gift !! value for money

My godson loved it

My daughter had fun making this kit. She needed help with the crystals as it requires boiling water. She had fun watching the crystals grow and arranging her sand. We grew crystals from a different type of kit and used them in the final set up because they were less messy, fit in the bowl better, and were more uniform than the ones we grew that came with this kit. The color on the crystals from either were not vibrant or uniform. The ones pictured in individual cups came with this kit. The ones on the sand did not. Daughter is happy and had fun that's all that matters.

I did this with my daughter. It was super fun to watch her run to the window every morning to see how big they had gotten. The only words of wisdom I have for this is be sure it is not too close to whatever is beside it. I had it on the window seal and it grew and attached to the window frame. It took a good 10 mins to get the color scrubbed off of the frame. Other than that it was pretty cool!

My niece said this was a really fun gift. Her mom wasn't exactly thanking me for some of the mess, but the end result was very cute!

The whole rest of the kit is super cute, but the crystals was REALLY disappointing. And obviously thats the point of the whole kit. We decided to follow the directions and go all out, letting the crystals grow for 10 days max. BIG mistake, but also apparently didnt matter." The solution was supposed to be completely untouched with good natural lighting, and we gave it that. But by day 2 the liquid seemed to evaporate a great deal. Day 10 I removed the solution and was left with a disk (size of the growing container) of extremely delicate crystals. To get everything to fit, I had to break off the crystals that grew away from the "rock" they were supposed tp grow on, before putting them into the terrium. It was just like trying to break off a millimeter layer of ice, super easy and brittle. We lost a LOT of crystals that way. In the end, all of the grow rocks were completely visible due to poor growth even after the longest allotted time. The crystals are VERY thin, ice density. I was very hopeful but I wouldnt buy again for the crystals.

Arrived on time and in great shape. Grand daughter loved it and was very proud to show me how it turned out after she had grown the crystals and put it together. She liked it so much, we got her a second one this year. She did need help from her dad in getting it set up. Highly recommend having adult supervision as chemicals are involved.

Très contente de cette achat ! Nous avons pris plaisir à le voir grandir ! Ludique, facile a faire et beau résultat. Je recommande

Preso per mio figlio di 6 anni, si è molto divertito a farlo, osservarlo nella crescita aspettando con pazienza e con orgoglio lo ha portato a scuola per raccontare e mostrare. Prezzo molto buono per il materiale contenuto. Consiglio anche se serve sempre la supervisione di un adulto.

facile da realizzare e molto bello da vedere…. abbiamo pazientemente aspettato una settimana che crescesse non siamo rimasti delusi…
