F4-41: DRUM AND CANDLE
Additional Info
- ID Code: F4-41
- Purpose: Demonstrate the circular vortex.
- Description: Place the lit candle on its holder about six feet in front of the opening. Tapping the elastic drumhead on the back of the box pushes air out of the hole. The geometry of the hole causes the air to assume the configuration of a rotating donut shape, like a smoke ring. The vortex travels rapidly through the air and blows out the candle.
- Availability: Available
