• 13:24, 14 April 2022 Physdemo talk contribs created page Reverb Cups (Created page with "{{NewDemo|subject=OWS|topic=Sound|file1=Reverb_Cup.gif}} Similar to the classic cup and string telephone except that this uses a spring. Shake the cup to send large waves down the spring and create sounds similar to whale songs or star trek laser blasts. Speak into the cup and the spring will create an echoing effect. A similar device is called a reverb when used with electronic instruments -- esp. guitars. '''Location: ''' * Shelf D-2")
