Product Description

We absolutely love this crystal growing kit from Thames & Kosmos. The 15 experiments progress from simple to complex, providing the perfect learning experience for new chemists. Grow dozens of dazzling crystals! A full-color, 32-page experiment manual guides your experiments in crystal chemistry.

From the Manufacturer

Grow dozens of dazzling crystals and conduct 15 illuminating experiments with this classic science kit. Experiment with four chemically different crystals each with different properties, including potassium alum crystals that form regular octahedrons, rapidly growing sodium sulfate crystals, long needle-shaped sodium acetate crystals, and plaster which is made from gypsum crystals. Mold fun plaster shapes, including stars, lightning bolts, dolphins, and pyramids, and grow layers of crystals on them. Use dyes to form colored crystals, and mix the dyes to grow a rainbow of custom colored crystals. Display your crystal creations in a clear treasure chest with a locking lid. Mold your own geode — a hollow rock with crystals growing inside — and create a beautiful crystal cavern inside. Experiment with growing crystals rapidly and slowly, and observe how that affects the crystal structures. See if you can grow one giant crystal, and many small crystals on the surface of a rock. Measure how the crystallization of solids out of a solution, and the dissolution of crystals back into solution, affect the temperature of the solution. Learn about the energy of crystallization. Investigate solutions, crystallization, and the chemistry of crystal growing. Learn about the structures and geometries of different crystal shapes. This kit is thoroughly tested and safe: Over one million units of this kit have sold worldwide. A full-color, 32-page experiment manual guides your experiments in crystal chemistry and Earth science.

Great Quality Natural Fabric Dress
Size: X-Large, Color: White
This dress was everything the reviews said - nice weight, well made, and great fabric. The suggested size matched my usual size, and it fit like a glove. That said, there was no extra room, and the fabric has no stretch. I’m 5'9" and prefer long dresses to be closer to ankle length, but this one hit at an awkward length on me. For the price, it wasn’t worth keeping, though I do think it’s fairly priced for the quality. Nowadays it’s hard to find clothing in cotton or cotton/linen blends, so I really appreciate that it’s not made from synthetic fabric.

Disappointing second one with a damaged zipper
Size: Medium, Color: Iceberg Green
This is maybe the 5th Drop linen dress I have purcahsed different version for my two girls and I and this is the second one I have received with a damaged zipper. It is disappointing they fit well and are well made . I am not sure if the last two I have received were returned items.

Nice quality
Size: XX-Large, Color: Black
Very nice fit and material. I’m a size 14 & the XXL fits well - maybe a tad bit big, but I didn’t want it to be fit uncomfortably tight either. My only complaint is that the side zipper gets stuck right where the pocket is. But I am able to put the dress on without having to open & close the Ipper.
