In the yard, outside, there was a chance to try to construct an earthfill dam,
And another to hear -- and see -- resonance (if you hit one pipe, you can see and hear others vibrating). You can also just run down the line and hit all of them, too.
There's lots more we can't show you here. They finally threw us out, at 5:00.
