How do the three seashells work? (Patreon)

After we filmed the Demolition Man reaction in January of last year, Toy made this prop for us. :)We have since then recorded another reaction to the movie with Abby ( https://www.patreon.com/posts/demolition-man-101761217 ) and now our friend Verowak Reacts watched the film as well. Her reaction premieres on her YouTube channel today. Check it out: https://www.youtube.com/watch?v=2i7w1GuLPAY
