I knew this mechanism would be useful. First the snake by Mr Cool, now an elephant trunk. Whatever next!

This is a rough prototype – a sort of proof of concept elephant head. Pull the tendon and the trunk raises. Rumpeta! Rumpeta!

Perhaps a fairly simple elephant. Pull the tail to raise the truck. I think that would be a charming little project.

I'll need to have a look at starting the trunk wider and tapering it, perhaps making each section a truncated cone. (For all you geometry geeks out there, the proper mathematical name for a truncated cone is a frustrum) 

Plan: finish off robot, make elephant, drink coffee.
