Hidden Messages - Goldenrod Pape

The term goldenrod is typically used to describe a color of paper - golden yellow. Certain brands of goldenrod paper contain a special dye that turns bright red in solutions that are basic like ammonia water or washing soda. The paper turns back yellow with an acid like vinegar or lemon juice.

Peanut Power

Peanut Power

A tiny peanut contains stored chemical energy. When we eat them, the stored energy is converted by our bodies so we can do work. We can also use the energy in a peanut to heat a container of water.

A flat panel solar cell

A flat panel solar cell

I made a more portable version of the solar cell in a flat panel form. I used the clear plastic top from a plastic CD jewel case as the window, and lots of silicone rubber glue to both attach the pieces together and to insulate them from each other.

Build a hydrogen fuel cell.

Build a hydrogen fuel cell.

A fuel cell is a device that converts a fuel such as hydrogen, alcohol, gasoline, or methane into electricity directly. A hydrogen fuel cell produces electricity without any pollution, since pure water is the only byproduct.

Make a solar cell in your kitchen

Make a solar cell in your kitchen

A solar cell is a device for converting energy from the sun into electricity. The high-efficiency solar cells you can buy at Radio Shack and other stores are made from highly processed silicon, and require huge factories, high temperatures, vacuum equipment, and lots of money.

The Plastic Hydrogen Bomb

The Plastic Hydrogen Bomb

It sounds like the perfect terrorist weapon, but it is a toy that teaches the principles of electrochemistry. It is also a high-tech squirt gun. The Plastic Hydrogen Bomb uses electricity to break apart water molecules into hydrogen and oxygen. Then it uses a spark of electricity to explosively recombine the gases into high pressure steam, which propels a stream of water high into the air.

Cross-Linking a Polymer to Create Everyone's Favorite Childhood Toy, Silly Putty

Cross-Linking a Polymer to Create Everyone's Favorite Childhood Toy, Silly Putty

The objective of this experiment is to cross-link a polymer and observe the changes in the physical properties as a result of this cross-linking. The changes in physical properties of a cross-linked polymer are also studied as the temperature is varied.
