Floppy Beef Curtains

The perfect crystal grow kit!

Reviewed in the United States on September 28, 2017

Style: 8 Crystal LabVerified Purchase

This is the best crystal grow kit we've ever experienced. We got a MASSIVE crystal grow yield from each of the colors. We used distilled water and had extreme attention to foreign particulates/dirt to the mixing/pan containers to ensure a pure solution. We let grow for about 5 weeks each or until the solution level reach the top of the crystals.

PROs: excellent crystal yield and the colors remain vibrant for a longer period than most kits. Materials provided were high quality. Sample stones provided were also really cool and a nice touch.
CONs: The crystals seem to leach salts onto the night light stand for a few days to weeks. We had to constantly clean the light stand off. Minor gripe. The leaching stopped after a few weeks and the crystals are fairly stable now.

I would buy this kit for all my friend's kids. It really is that awesome.

You can get the same kit for almost $20 less. Search Ultimate Crystal Growing Lab – 8 Colors to Grow and Light-up Display! Only difference is it doesn't have the Nat Geo name on it.

A great teaching toy

Reviewed in the United States on January 6, 2017

Style: 8 Crystal LabVerified Purchase

We bought this kit for a Christmas gift and it was a big hit while we were setting up the experiment. You get 8 crystal mixes and seeds to work with and four silicon growing chambers. You will need to have a space set up where the chambers can sit for 7 to 10 days for the crystals to grow without being moved. One word of advise DO NOT US ALUMINUM CONTAINERS TO BOIL THE WATER AND DISSOLVE THE CRYSTAL MIX. The aluminum will react with the mix and you will end up with crystalline cotton candy instead of crystals shown on the box. The company Discover with Dr. Cool sent us a replacement crystal mix and seed to replace the botched crystal.

Wow! I'm so amazed how great this worked!

Reviewed in the United States on January 9, 2018

Style: 8 Crystal LabVerified Purchase

Ok so this kit takes a bit of effort but WOW the results are stunning! I bought this for my 6 yo daughter for Christmas. We set up the first 4 crystals per the directions and let them sit 10 days. We had fun looking each day to see how big they were.

After they were done, I removed the crust from the edges of the cup, poured off the liquid, and eased the crystal out of the cup. They came out easily.

To get the seed rock out, I used a razor blade, went around the edges and flaked off the crystal growth to expose the edges, then used the corner of the blade to pop the rock out. I was veeeery careful and all 4 crystals came out intact!

It takes patience but totally worth it, the resulting night light is a treasure she will probably keep for life.

End results are beautiful

Reviewed in the United States on September 21, 2018

Style: 8 Crystal LabVerified Purchase

I initially bought this for my niece but it was so tempting that my niece never knew about it 😈. It's fun and end results are pretty. Boil water, pour the boiled water in a bowl (exact water level marked on each cup), add the powder and stir until all powder is treated. Pour the solution into the cup, wait for 12 minutes and then drop the seed carefully into the solution. Place the cup in a dark area and keep it steady and untouched for 7 days. My end results are in the photos. Removing the seed is not that tricky, u need a knife and u need to remove the crystals forming around the seed edges. Once those are removed, stick the knife in between the seed and the crystal and gently remove the seed, crystal will be delicate at this time. Avoid cleaning the seed or exposing it to pressurized water directly when out of the cup.

I now have a very disappointed kid

Reviewed in the United States on August 28, 2018

Style: 8 Crystal LabVerified Purchase

After a week of very still conditions, and exactly the same amount of starting boiled distilled water, ONLY ONE of the crystal seeds actually produced a rock. And that rock looks nothing like the pictures on the box. So, forget the night-light stand. With only one crystal produced you can basically throw the night-light in the garbage. I suspect the starting materials were already stale. The bags felt lumpy, like they were already absorbing moisture long before they even left the warehouse.

I'm disappointed.

Reviewed in the United States on April 26, 2017

Style: 8 Crystal LabVerified Purchase

So, it did come with instructions. However, the instructions did not say anything about the kind of cookware you should involve when warming and dissolving the materials. When I went looking for help on what was wrong with my crystals, I found other comments that said not to use aluminum pots. So, I contacted National Geographic very soon after receiving them. They said they would send out replacements. I have yet to receive them nor contacted by National Geographic. I'm disappointed.

Pricey but interesting toy!

Reviewed in the United States on March 10, 2018

Style: 8 Crystal LabVerified Purchase

This was more pricey than what I normally spend on a 'toy' so I was hoping that my splurge would not be in vain. It was given to my 8 year old daughter for Christmas and she was excited when she saw it. The instructions were clear and the growing cups were of good quality. We left the crystals in for 11 days (it recommends 4-10 days) and they were very developed and beautiful once we took them out! The colors of the crystals were not as vibrant as in the pictures though. They were very lightly colored, only slightly more than white. The "seed" rocks (what the crystal grows on) were very difficult to remove and even though I was as careful as possible, the yellow crystal dissolved and broke apart in my hand while I was trying to extract the seed rock. (The seed rocks only need to be removed if you want to display the crystals on the lighted base so that they can light up from the LED's underneath them, otherwise the seed rocks can be left in the crystals). I like that the kit came with more crystals to grow than there are spaces on the lighted base (I think there are 7-8 different colors?) because it gives my daughter options of which she wants to display and change around and you know we girls like changing things around :) Because of the expense this is probably a one-time buy.

My 8 year old son loved it!

Reviewed in the United Kingdom on November 29, 2020

Style: 6 Crystal LabVerified Purchase

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.

Fun family activity - patience required

Reviewed in Canada on February 4, 2020

Style: 8 Crystal LabVerified Purchase

Bought this for my young son and he loves it. It's definitely an 'adult assistance required' product though. That shouldn't disuade anyone though, just give them realistic expectations. As long as instructions are followed exactly (boiling hot water, stirred immediately, dissolved all powder, seed stone FLAT on bottom) you'll have a good time. That said.. The seed stone is still tricky after our 6th crystal. I recommend a sharp, small paring or steak knife. (Instructions recommend a spoon but no.. Just no) Gently scrape away any crystal growth that grew over the outer edge of the stone until it's all clear. Don't fret little bits that fracture away as you do this if it happens. Once that's done gently insert the tip between the stone and the biggest piece of crystal. Only a bit though such that the depth is barely measurable. Gently pry. You'll likely fracture off a piece of crystal, the stone, or both, and if that happens it's no matter, just move opposite that spot and repeat. Then in quarter turns keep trying till you get it. Keep a firm but steady grip around the base while you do this. Don't crush the gem, but dont risk dropping it.

As a gift to someone, I'd recommend against it because it's really something you should knowingly get yourself into. I'd hate to get a child excited at the prospect of growing crystals only to have their parent fail for lack of interest.

So disappointing

Reviewed in Canada on May 1, 2018

Style: 8 Crystal LabVerified Purchase

I bought this for my granddaughter for Christmas and she didn't get around to completing it until after the 30 day refund. It started off looking like it would be wonderful but after creating the crystals, the bottom part that is supposed to just 'pop out' wasn't even in the crystals. The crystals don't sit flat over the light fixtures and you can't see the light through them. Requested a refund but was denied because it was past the 30 days. I'd be happy to mail the whole thing back to them so that they can see that their product is garbage. Save your money and buy something that works from a company that values its customers.

Was really fun for kids to setup and watch the crystals grow, but trying to remove the seed rock was impossible, the crystals fell apart, like they were held together with compressed sand. It was horrifying to watch my sons face full of dissapointment when every single one broke.

Good but very fragile

Reviewed in Canada on January 20, 2018

Style: 8 Crystal LabVerified Purchase

These are pretty cool even for the parent to see haha. Our kids have really enjoyed watching this transformation take place. They grow quite well, but the seed rock is very tricky to remove and the crystal is very fragile. It's difficult together out without losing some of the crystal.. we have 2 that are taking a very long time over 2 weeks now to even reach half the size of the others and for some reason those two do not match the color on their package. However all in all so far a good product.
