POLYMERS
The Wacky World of Superabsorbent Polymers— Chemical Demonstration Kit
Pour distilled water into an “empty” cup and the water solidifies into a gel. In a beaker, add a small amount of powder, pour in distilled water and see an avalanche of fresh powdered “snow.” These sodium polyacry- late polymers have many applications. AP6303 | $17.05
Water Marbles—
Mystery Nylon Factory—
Polyurethane Foam System—Chemical Demonstration Kit
When these substances are mixed, a rigid foam is produced. The volume of foam produced is 20–30 times larger than the original mixture. Experience the excitement of polyurethane foam! C0335 | $35.20
Look around—is there anything that is
not made of a polymer, either natural or manmade? The six experiments and five demonstrations in this outstanding lab manual will help students see chemistry not just in a textbook, but in the world around them.

Chemical Demonstration Kit
Chemical Demonstration Kit
Amaze your students by “floating” a steel sphere on “water.” Since the water marbles have essentially the same refractive index as water, the steel sphere will appear to float. Learn about the refractive index of water and the properties of polyacrylamide spheres while also calculating how much the spheres have “grown.”

AP7429 | $21.40
Two solutions are poured together in a beaker. A paper clip is lowered into the solu- tion. As the paper clip is withdrawn, almost by magic a very long strand of nylon is pulled from the beaker. A super demonstra- tion to discuss polymer concepts. Teacher Demonstration Notes included.
