How to get an egg in a bottle! You need a hard-boiled egg, a wide-mouthed bottle (just a bit narrower than the egg), and a match or strip of paper. As the paper burns, the air in the bottle warms and expands. After it goes out, the air cools again and contracts, and that draws the egg inside.

Not all shadows are black. The Colored Shadows exhibit is a discovery of the colors hidden in white light. Red, green and blue spotlights shine on a wall. The wall is white because red, blue and green light combine to make white light. These colors are often called the additive primary colors. As you walk (or dance) between the lights and the wall, your body casts three different shadows. 

Materials: 1. Water 2. A clear plastic bottle with a cap 3. Dish washing soap 4. Glitter Steps: 1. First, fill the bottle until it reaches 3 quarters full 2. Next, add 3 drops of dish washing soap in the bottle. 3. Then, sprinkle in 3 pinches of glitter. 4. Next, put the cap on tightly 5. Finally, turn the bottle upside down. And hold it by the neck. Quickly, spin the bottle in a circular motion for 10 seconds and stop to see a mini tornado in your bottle. Lesson: When you spin the bottle, it creates a water vortex. The water is spinning around the center of the vortex because of centripetal force. Centripetal force is an inward force directing an object or fluid towards the center of its circular path. Examples of natural vortexes are tornadoes, hurricanes, and waterspouts.
