This kit enables users to build virtually all simple molecules encountered in organic chemistry. Includes space-filling models that simulate the true shape of saturated compounds. Provides open models that form realistic single, double, and triple bonds — even strained rings. Allows smooth rotation of the bonds to make conformational analysis easy. Contains enough components to create several models at once. The components are precision-tooled from quality plastics, are virtually indestructible, and come in a sturdy plastic case for easy storage. Provides a useful Instruction Book — with photos, diagrams, and concise discussions of chemical principles.

In other reviews there were a couple of complaints about the kit not being realistic. However, the bond stiffness and design are surprisingly realistic (molecules aren't all that flimsy). The kit is perfect for create virtually any small organic molecule. It is excellent for seeing the difference between a chair and boat conformation, provided that it is put together appropriately. (My organic book and the directions were useful in arriving at the right conformation when I had problems.) The kit may just take a little bit of time to get used to, but it definitely is worth the work and time to see molecules in 3-D!

The pins representing the bonds hardly fit the atoms. They don't allow for any rotation around the bond axis (exept by deforming the pin and introducing awkward stress in the molecule. Almost impossible to build a good model involving a ring structure.
There is a special tool to get the pins out. Don't lose it.

For a non-specialist like me, it's a bit daunting to try to develop intuition about how simple molecules are put together. It really helps to have a physical model, especially for subtle ideas like multiple stereocenters and 3D structures. This kit is a great way to help visualize and understand simple chemical systems.

It comes with 14 carbon "atoms", 4-holed black beads, and a collection of others: 2-holed oxygen, 3-holed nitrogen, and 1-holed hydrogen and halogens, all color-coded. The number of holes represents the typical valence of each atom type, but you can assign any meaning you want to the color code. Two kinds of connecting "bonds" plug into the beads: long flexible ones for stick models, and short ones that place the atoms butt up against each other for space-filling models.

The pieces snap together snugly, so the assembled models can stand a bit of rough handling. Someone with weak fingers might have a tough time pulling them apart, though. There are enough pieces to make lots of different models: sugars, amino acids, and other small, biologically important bits. I could ask for beads representing phosporus (needed for DNA) and sulfur (for aome amino acids), and there's always reason to want more of everything. Still, this is fine as a beginner's kit. And, as a desk toy, it lets you look like you're doing real work.

Why are none of the elements pink?   May 6, 2002

While the molecule kit allows you to make lots of fun molecules, it just doesn't provide enough creative freedom...though the fun popping noise you get when you pull the molecules apart is quite amusing. I found these overall pretty useful in class, but would not recommend eating them. The nitrogen goes down a little rough.
