 | Can we create light by chewing?
Certain chemical bonds will generate light energy when the molecules are torn apart by mechanical crushing. Wintergreen Lifesaver candies contain some of these bonds. No other flavor of lifesaver candy (such as peppermint) will work in this experiment. |

| Can you demonstrate why the sky is blue?
The scattering of light by the atmosphere, which creates the blue sky and red sunsets, can be modeled when light from a flashlight shines through clear glue sticks. |

| Demonstrate how satellites measure the amount of energy reflected from the earth
Satellites are used to monitor the condition of the earth's surface over large areas in a short time period. Images from satellites have been used to determine changes in global vegetation patterns, monitor the health of agricultural crops, and measure the amount of evaporation from the earth's surface. The pictures from satellites are not taken with a traditional camera that requires film. Instea |

| Does the viscosity of liquids affect the shape of droplets?
This experiment involves the observations of different shaped drops of liquids of varying viscosities. The purpose is to observe and compare these different forms. The hypothesis is that the liquids with the higher viscosities will form longer necks on their drops than the liquids with lower viscosities. |

| How can we separate and detect infrared light?
In the year 1800, Sir William Herschel discovered the existence of infrared by performing an experiment very similar to the one we show here. Herschel passed sunlight through a prism. As sunlight passes through the prism, the prism divides it into a rainbow of colors called a spectrum. A spectrum contains all of the colors which make up sunlight. Herschel was interested in measuring the amount of |

| How to make a glass sphere microscope
Events happen in nature in many dimensions. Most of them pass unnoticed by observation because their scale is too big or too small. In fact, we would have to be giants, to follow the path of clouds over continents! And who knows how big we should be, to be able to contemplate the majestic rotations of our galaxy! On the contrary, if we were as small as an ant, we could see the amazing miniature wo |
