ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************
I'm looking for a material which could be used by visitors in a workshop or class (minimum one hour in length) to make sundials suitable for installation and use outside.
So the material needs to be:
weatherproof (waterproof, rigid, able to take a pigeon landing on it, a cat attacking the pigeon, and a blast from a garden hose intended to discipline the cat)
easy to work with (lost-wax bronze casting is out)
cheap (clay is cheap but this museum does not have a kiln -- there may be one nearby)
I'm out of that wonder material, unobtanium, and I'm looking for a substitute.
