Pendulum Power!

Sat, 19 Aug 2017

One of the discussions that come up from time to time when talking about paper engineering is allowable materials. Can you use string? What about cocktail sticks or skewers? I have come down on the side of pure paper apart from the occasional coin to add weight and maybe a rubber band for tension. There are a few models on the site that use coins as pendulums. Among them, the nodding cow.

The Mk I pendulum powered cow uses a coin concealed within the cow’s body to make the head nod up and down when the cow is moved. (Moo-ved?)

After a suggestion by Michael42er I released the MkII Pendulum Cow which also had a swinging udder. You can download and try both these models by clicking on the images

    I’m very fond of this blue colored cow for some reason. Is the Nodding Cow available in the blue color?
