This is a video of the downward spiraling helix train run built from over 8,000 K’Nex pieces and Bachmann EZ track, with an HO model train chugging down the spiral (previously: this other infinite spiral train set). And speaking of infinite downward spirals– “Your life.” How have I not hit the bottom yet? I’m like a rock thrown down a well that never makes a splash. “Except traveling in a spiral.” Exactly. “And a turd instead of a rock.” That goes without saying.

Keep going for the video.
