HOW CAN YOU MAKE A CUP SOUND LIKE A DUCK? ALL YOU NEED IS A PLASTIC CUP, SOME STRING, A PAIR OF SCISSORS AND A WET CLOTH!
The wet cloth creates friction on the string which produces a vibration. You can hear a faint squeak on the string with no cup on the end. When you add the cup, this amplifies the noise, creating a much louder sound.
HEALTH AND SAFETY
If the children are making their own, they should use children’s safety scissors.
