We had this in the 8th grade science class, and IMO it was much better than this Harvard version. Still PB&J with instructions. Teacher had a skeleton named "it". Anytime instructions referenced the word "it", the teacher used the skeleton in place.

Not in that course, but I've done it at a "STEM" day; it's just about the most fun I've ever had teaching.

That's awesome.

I got the sense the professor liked it a ton too. In the videos of this on YouTube you can see the professor really enjoying watching it all go down.

It still is so memorable.

I had a middle school art teacher do it in roughly 1995.

We did it in 3rd grade in public school.
