The tea driven automata that I previously made from cardboard has now been photoetched in thin stainless steel and hand painted. These are now available for sale through my Etsy shop.

Once the automata is placed on top of your tea and left for 40 seconds, a little starting rotation of the axil and he will peddle for approx 90 minutes.
