I am a substitute teacher. I've been working the last few weeks with 6th, 7th, and 8th grade orchestras.
Now, some of the 8th graders are pretty cool, so there's a handful of them that I write passes for to practice and chill in the orchestra room at the end of the day, so they aren't drooling over their desks or stabbing out their eyes or cursing the hands on the clock in study hall.
(Mind you, I am doing all of these things in the study hall I have to supervise. lol)
On Friday, at the end of the day, the band teacher and I went into the orchestra room, chatting as we went, and were suddenly stopped by this feat of awesomeness:
Band Director: Yep.
Me: I can't believe they got them to balance that way.
Band Director: I'm not sure if we're teaching middle schoolers or college kids.
The thing was like a house of cards, so we tore it down carefully.
Out of pure curiosity, I had to try this myself, so I tried to stack the chairs by the legs just to see how difficult it was. It was really tricky!
