This person asked a girl with a hearing impairment guess sounds of soundless things.
They gave her a cushion and made her squeeze it, then asked her to guess the sound.
When they did the same thing with a cotton pad, the girl guessed that they were messing with her and laughed away.
They then made her guess the sounds of beads, an electric switch turning on and off, and ice cubes being dispensed, among other things, all of which she guessed absolutely right.
