Did your washers, nuts, and pennies change color? Where do you think the color came from? Is there a difference between pennies dated 1982 and earlier, which are solid copper, and newer pennies, which just have a coating of copper?

You can also use washers and nuts that were not placed in the solution for a silver-color contrast. 36 SuppLies ZSVNANVKR ZRONNM ZR@KS Z@SKD@RSODMMHDR HMBKTCHMFRNLDEQNL @MCADENQD ZAQ@RRV@RGDQR ZAQ@RRMTSR ZV@SDQ ZO@ODQSNVDKR ZDLAQNHCDQXSGQD@C 0\\Y

Explosives are materials that, once ignited, burn very fast, releasing lots of energy and producing a huge amount of hot gas. An explosive has molecules with weak bonds. A little bit of energy, like lighting a match, ignites the explosive and breaks those bonds; that’s the activation energy discussed below. The atoms rearrange themselves and form stronger bonds and, in the process, release lots of energy. An explosive is unstable because the molecules are packed together tightly, so it doesn’t take much to break some of the bonds.

The smaller molecules cling to water more, so they travel farther along the paper before attaching to the paper. Looking at your paper, which pigments do you think have larger molecules? Scientists use different types of chromatography as one way to figure out exactly what is in a substance. They use equipment that is more precise than your chromatography setup, but the principle is the same. Just like your name, when you sign it, looks different than everyone else’s, each chemical has a “signature” that is different from other chemicals; it will travel along paper for a specific distance.
