Booth Activities 

Chemistry in a Bottle - Are you familiar with the dynamic density bottle experiment? This interesting experiment was invented by Lynn Higgins, and is sold by various science supply companies. Two immiscible liquids (usually salt water and isopropyl alcohol) and two different types of plastic pieces are contained within a dynamic density bottle. The plastic pieces display curious floating and sinking behavior when the bottle is shaken. 

Soap Boat 2.0 - The soap boat experiment makes use of the Marangoni Effect, the tendency of material to move from a region of low surface tension to a region of high surface tension. Because detergent has a lower surface tension than water, when a drop of detergent is added to the fuel reservoir in the boat, the surrounding water “pulls” the soap out of the reservoir. The flow of soap out of the reservoir provides thrust to push the boat forward.

How Does an Orange Peel Pop a Balloon? - Some orange peels can cause balloons to pop. The compound in orange peels called limonene is responsible for this effect. Limonene is responsible for the wonderful smell of oranges, and it is a liquid at room temperature.

How Do Color Changing Marshmallows Work? - The color of these marshmallows changes when exposed to heat: the blue version turns green, while the pink version turns orange.
