I took the kids to the Museum in Kitchener, Ontario. They had an Easter egg hunt. But there was also a hockey exhibit. Check out this display. You put your face up to the goalie mask and look inside. Then you press a button.
You know how when you get hit in the head, you hear it but don't really FEEL it? It's the same shocking feeling that this contraption gives you. After I tried it, I felt like I'd been hit in the face for realz.
