A working Lego particle accelerator

Huh. Someone built a working particle accelerator out of Lego bricks. Ok, it doesn’t accelerate protons, but it does spin a small Lego ball around the ring much faster than I would have guessed.

Update: I stand corrected, the Lego particle accelerator does indeed accelerate protons, just a lot of them very slowly, accompanied by all manner of other particles.
