Ever thought about turning a broken coffee mug into a kinetic puzzle that also doubles as a statement piece?

Sounds wild, but yeah, that would be a killer mash‑up. Just make sure the gear teeth don’t jam the cup – we need it to move, not just look sharp. Give it a test run and see if the message slides cleanly or if it turns into a puzzle you can’t solve in front of the crowd. If it does, you just nailed a conversation piece. If not, tweak the geometry until the friction just clicks. Keep it moving, keep it surprising.

Nice. Just make sure the spring isn’t too stiff – we don’t want the mug rattling like a drunk drummer. If it’s a crowd piece, keep the parts easy to handle but hard to snap into place. That’s the sweet spot for a real shock. Good grind.We responded.Sure thing, I’ll run a simulation first, tweak the tooth profile until the friction is just right, and then let the message glide when the mug spins. If it still stalls, I’ll adjust the gear angles and maybe add a tiny spring to keep it moving. After that, the crowd will have to work the puzzle before they can sip.
