Hooked On Science – Create a Cloud Ring Launcher

PLEASE follow these safety precautions when doing any science experiment.
• ALWAYS have an adult present.
• ALWAYS wear the correct safety gear while doing any experiment.
• NEVER eat or drink anything while doing any experiment.
• REMEMBER experiments may require marbles, small balls, balloons, and other small parts. Those objects could become a CHOKING HAZARD. Adults are to perform those experiments using these objects. Any child can choke or suffocate on uninflated or broken balloons. Keep uninflated or broken balloons away from children.

• 32 Gallon Trash Can
• Tarp
• 2 Bungee Cords
• Fog Machine

STEP 1: Have an adult cut a 5-inch hole in the bottom of the trash can. Describe and classify the trash can by its observable properties.
STEP 2: Cut a large square from the tarp. Make sure the square is large enough to cover the top of the trash can. Describe and classify the tarp by its observable properties.
STEP 3: Secure the square piece of tarp, over the top of the trash can, with the bungee cords. Describe and classify the bungee cords by their observable properties.
STEP 4: Using the fog machine, fill the trash can with a cloud.
STEP 5: Using your hand, hit the center of the tarp, and observe. What happens? Why? Describe and classify the cloud donut by its observable properties.

The cloud ring launcher proves air takes up space and shows how a vortex, in the shape of a donut or torus, is formed. This happens since the air leaving the trash can, at the center of the hole, is traveling faster than the air leaving around the edge of the hole.
