Good
I bought two as a gift. When making them, one grew as normal and turned out nice, but the other developed crystals on the top which than fell down and prevented it from growing anymore. These were nice crystal growing kits for the price!

Fun gift
My 11 year old grandson was very happy to get this. It should give him some satisfying hours making crystals. Very pleased with this.

Way Smaller than pictured
It grows a third the size of the picture.

Nice, inexpensive little activity.
Cute idea with an orientation towards STEM curriculum. Takes about 15 minutes to assemble and in a few days, the crystals almost filled the little jar. However, they didn't glow very strong. Lasted about 3 weeks before they started to break down.

Cool project!
This was a Christmas gift to my daughter and it was a great gift. It is recommended to rinse and replace the water after 7 days but we let it sit for longer like 12 days and the crystals grew a lot more. Very cool idea for teens.

Funny Experiment
Funny expriment, the seed rock doesn't sink easily, it keeps on floating so that is my only issue. The crystal is growing beautifully, these photos are taken after 3 days, will wait 7 more days and see the results. Glowing doesn't last long, if someone is wondering.

Cool, easy and fun
Really cool little experiment to do with the little ones. Better for older children maybe 4 or 5 and above for there is a lot if "waiting" for it to grow(8 days total). Easy to follow instructions and everything included.

Cumple su función, a mi hijo le encantó
Es pequeño, pero funcional, mi hijo se entretuvo haciéndolo, si tardo en hacerse todo el día, y en la obscuridad brilla bastante bonito
