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.

Excellent quality and value
This is my 4th Maelreg 1/4 zip shirt. I've lost a lot of weight and looking for clothing that fits well and doesn't feel like a shirt from China. I found that the quality and fit are excellent. The fabric is soft, well made and slightly heavier than other 1/4 zips I've purchased on Amazon. The weight of fabric gives a quality feel. The styles of Maelreg pullovers are great. I get a lot of compliments on these shirts.

MAELREG Clothing Looks Great!
Love this quarter zip. MAELREG makes some comfortable, sharp looking clothing. Their golf apparel is fantastic. The value is worth it. Their shirts are true to size. I am 6', 215lbs and wear an XL, which fits nicely.

Great for Tall Guys
I got this for my husband, he has a pullover that he has worn for years and it needed replacing. Finding one like this that was lightweight and loose fit was a big challenge. He loves the quality and fabric and its not hot but still helps when their is a breeze or chill. I liked that the color and pattern are versatile for all seasons. He is 6'5 and it actually fits his torso! Just get it!

It’s a hit!
Color: Brown Grey Camo, Size: Large
I picked on of these up after seeing it online. I have multiple Maelreg items and all are great quality. They are my go to golf and casual clothing brand. Super comfortable, soft, light weight, and perfect fit. Olive on the east coast and this color is all the rage in the area. These are some of the best value 1/4 zips out there.
