Here’s some more ideas for a “sound” scavenger hunt. We’re actually doing this with a college crowd, but all sounds are appropriate for younger ages too. Pop-can opening, cards being shuffled, someone saying “I love you” in a foreign language, video game in an arcade, 10 toilets being flushed, have a random passer-by say their name and describe their shoes, a store clerk singing a silly song, a sneeze — double points if it’s REAL.
Good luck — Daryl
