4M Crystal Growing Kit | Fun STEM Science Experiment Set to Grow Your Own Vibrant Crystals at Home | Educational Chemistry Activity Toy for Teens Aged 14+ | Screen-Free Learning & Discovery

I didn’t know what to expect, but after 2 days a huge crystal had already formed, just the colour my daughter wanted. We couldn’t believe it, it’s beautiful and fascinating. The only issue is that now I have to buy more ;-)

Alot smaller box than what i was expecting. But it will do for my granddaughter for xmas

Every child loves a gem / crystal and this is no exception. Brought as a present several times and children have taken their crystal to school as show and tell. The crystals are a bit delicate and easily break if handled, so need to stay in container.

I felt I had to write a review, as I went ahead and bought this despite the bad reviews as my 8 year old son really wanted one. I'm not quite sure why the other people who gave it one stars did not manage to grow any crystals as we grew the most beautiful crystal - very much like on the box. Once you have put the lotion together it is important not to disturb it for a while, maybe this is why some people did not manage to grow the crystals but we left ours completely still initially. My son has kept the crystal and has it on display - he now wants another box to do a different colour!

Didn't work followed the instructions but nothing really happened only a couple of crystals on the side of the tub nothing like in the pictures

Was easy to set up, enjoyed doing it

Good present for a friend

I can't really review this 100% accurately as I messed it up. But overall it's decent, my little sister loved the idea of it growing and even though I really ruined it, It still grew around the top. It may be a little difficult for a child to do on their own especially with the boiling water. So make sure to read the instruction unlike me. I was a little disappointed you only get enough kit for one crystal. The box is a lot smaller than I thought, but never the less my little sister was happy with it and that's all I could of asked for.

子供の頃類似品で、結晶作りをしたことがあります。 2回目のチャレンジでした。 説明書は英語ですが、大きいイラストでわかりやすく書いてあるので、翻訳アプリを使わなくても簡単に作成できます。 結晶の色を自分で決めれる点と、 価格とメーカーの信頼性が購入の決め手でした。 満足です！

My daughter loved it!!!

Il prodotto è arrivato nei tempi previsti, purtroppo le istruzioni e le scritte sulla confezione sono solo in polacco 😖. Appena riusciremo a decifrarle proveremo a creare cristalli

Just cluttered chemicals, no actual crystals. See the photo attached. Nothing like some of the better competing products on amazon.com.

Good gift
