The Mould effect

0% to do with politics, polling or the media.

But 100% fascinating and fun.

The Proceedings of the Royal Society A includes this technical discussion of what’s really going on.

  1. Enjoyed the video. I’m a retired chemist who worked a lot on polymer structure and properties and hadn’t expected to come across fun polymer physics on your site.
    Not convinced by the model however, too simplistic. But being a chemist I’m an experimentalist more than a theoretician.
    So first I’m pleased that Steve Mould had an experimental observation named after him. But I would like more data before trying to model it theoretically. I would have liked to see the effects of different density, linkage lengths and diameter balls. Also what is the effect of the density and viscosity of the surrounding medium, both in the initial beaker and in the receiving one – do the chains still syphon? Or is the difference between plastic and metal more to do with the ball hardness or the bendiness of the links?
    Might be a fun project for ‘A’-level physics and/or chemistry students.
    Perhaps this is me being too liberal – must look further, think of the other etc!
