When you're completely overwhelmed and just can't take it anymore, save your voice and press this Panic Button. The blood-curdling scream that issues forth will express just how you're feeling without shredding your vocal cords. Also great for Halloween or church. Each 4-1/4" x 3-3/4" x 3/4" (10.8 cm x 7 cm x 1.9 cm) plastic device has a hole in the back so you can hang it on a wall. Requires two AAA batteries (not included).
