HINTS: Be sure your water reaches & stays at rolling boil (100°C /212°F) before dissolving the crystal powder in the water. It took a couple cycles through our electric kettle, so that the water stayed near 90°-100°C long enough in order be able to put the first packet of powder (monoammonium phosphate) to "super saturate" the solution. CAREFULLY -it's so hot- Stir in first crystals until ALL dissolved. THEN WAIT UNTIL WATER/crystal solution DROPS IN TEMP TO 40°C. This took like 20-30 min. That was hard for my 7 yr old, but we made it fun by checking the solution temp every 5 min. THEN at 40° C add your "color powder" of choice. If Making pink, light blue or purple, follow the included CHART with how many scoops of each color to put in. We made LIGHT BLUE= 1 scoop blue powder (aluminum potassium sulfate, sodium chloride & blue color) AND 3 scoops white powder (aluminum potassium sulfate). DO NOT STIR!!! Do not cover. DO NOT BUMP OR EXCESSIVELY MOVE the included container with solution in it at this point. IT NEEDS TO SIT STILL, uncovered & UNDISTURBED @ ~ 68° F for at least 24-48 hrs. If the room is colder it takes much longer. I've heard up to several weeks if the room is cold. They recommend placing it on top of your refrigerator. It's warm there and it won't be bothered by anxious hands & pets. THE COLORING POWDERS DO STAIN clothes, furniture, etc. We had great looking crystals in ABOUT 48 hrs, but waited to see if the crystals would go above the "water line". (They did a little). Use a flashlight/torch to check on crystal growth in the colored water solution, as it can be a bit hard to see in the dark colored "water".
All in all, great fun and great results. Can't wait to try again in a different color. I think the MSRP is a bit expensive for this kit, but I've seen it on Amazon for less (about half) & consider the education & results we've had as well worth the lower price.
What a FUN and NEAT little project this was! I bought this because my 8 year old grandson was coming for a weeks visit and I thought he would enjoy growing his own crystal! And he did!!
The instructions are a little confusing but after reading other reviews I was able to figure them out. We ended up growing a purple one. It took about 4 days before I even noticed anything growing and by day 7 we had our crystal. I was a little worried I did something wrong but it was finally there! It says to place in a high, warm place but the only place I had was inside my microwave. My microwave sits above my stove and it's always warm inside of it. Seemed to work good. The results are pleasing. My grandson asked if we could do another one.
This is a great product and would make a great gift for anyone who loves science, rocks, crystals or growing things.
If these are really for kids please make the instruction clearer!
