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.

Well made but on the small side. I recommend ordering one size bigger than your usual size
Size: Large, Color: Pure Black (Retro Rose)
The fit on this shirt ran slightly smaller for me being a slim fit, so I order the next size up. Getting the next size up gave me a perfect fit. The material is soft and comfortable. I will likely consider similar shirts in the future. I recommend the product.

Very nice shirt -Good Quality
Size: XX-Large, Color: Red (Retro Rose)
My husband is 6'1, weighs 178 pounds and normally wears a medium or large. Just for reference his pant size is a 32-34 depending on the brand. We ordered a large due to the fact the shirt appeared to be fitted more at the waist and from looking at the description I knew it would not have much stretch due to the satin type material. I was right. The large fit perfect and hung well. My husband use to be very large in shoulders and arms, but with age he has lost muscle mass, and recently lost a lot in his belly, so usually mediums fit perfect now. But when he put his large on, a medium would not have fit good to be comfortable & give proper fit in stomach area, so glad we went with the large. The shirt was purchased to go on a Virgin Cruise for Scarlett night, and he plans to wear black pants with it as in the picture the company posted, and this shirt will be perfect for that. It is a nice shirt, good quality, and if someone wanted it for an event/cruise or just for a night to dress up, especially for a Caribbean/Spanish or Latin dance theme, this shirt is a perfect look to me. Buy it, you will not be disappointed. He has not worn it yet, not washed it, but I would not put in it with other colors, may fade a little like reds do, and definitely, only dry on low/delicate. May need a pressing/steaming, but overall, it was not horribly wrinkled when we received it. A toss in the dryer may just do the trick. Was delivered on time as it said it would. Hope this info helps you.
