After I graduated, my first real job was as a research solid state chemist. For this work, we often had to have specialist apparatus made from glass or silica. We had a team of glass blowers available in the Glass Workshop who were simply the best. They could make anything you wanted. I strongly suspect they could have made one of these if asked……

Janus, the post title says it all. It’s brilliant. What did you think I meant; that I was transparent or just full of hot air?
Sipu : And there was me thinking you meant that you made a lot of noise and did little useful work!
Better than being tagged ‘viscous’ – thick and immobile.
Janus: Being Viscous gives one a certain “Poise”
and many viscous objects are also Thixotropic, some even Bingham bodies. 🙂
