Doppler Rocket


Doppler Rocket Demo Picture

Two people required to use this demo. Each person holds set of handles, and unwinds rope (about 20 m) . When one set of handles is quickly separated (handles initially held together, then quickly pulled apart) the football shaped “rocket” is forced to slide down the ropes. The rocket contains a noise maker (turned on manually) that exhibits Doppler shift when in motion. Users take turns launching and catching the rocket. Doppler affect can be heard by audience members in close proximity.
