Molecular Model Set, 1" Atoms, 104-piece
We searched long and hard to find the best wooden models avail- able—and we found them! This inexpensive set of 1"-diameter wooden atoms, wooden pegs, and springs will last a lifetime. The 1⁄4"-diameter springs and wooden pegs fit snugly in the atoms so your molecules stay together. Painted in vibrant colors, these easy-to-manipulate wooden balls represent atoms which can be built into an infinite number of molecules. The 104-piece organic structure set includes:
• 28 hydrogen (yellow) • 10 carbon (black)
• 6 oxygen (red)
• 4 chlorine (green)
• 2 sodium (orange)
• 2 potassium (purple)
• 30 11⁄4" wood bonds
• 10 21⁄8" wood bonds
• 10 2" spring (double) bonds
• 2 nitrogen (blue)
Replacement bonds available in packages of 12; see below.
