When I was a grad student, I used to keep a basket of burr puzzles on my coffee table for guests to fiddle with. Today we'll look at an activity where students design them before solving them!
My colleague Daniel Kline has been playing around with a novel set of puzzles to be solved with a Soma cube that should hopefully hit the website in coming months. I wanted to create something that was less reliant on gravity and friction and ended up with a slightly more traditional puzzle set.
