STEP 1: Utilizing the nail, push a gap within the backside of the cup.
STEP 2: Thread 3 ft of string, by way of the outlet, within the backside of the cup, tie a big sufficient knot, within the string, so the string doesn’t pull by way of the cup.

STEP 4: Utilizing the illustration of a sound wave, to the fitting, beneath “science background,” develop a mannequin of a sound wave with the pipe cleaner. Determine the completely different elements of the wave.
Sound is vibrations transferring by way of matter. Squeezing and pulling the sponge down the string creates vibrations. The cup amplifies the vibrations permitting you to listen to what feels like a turkey.
