The Astonishing Benefits of Educational Television
There was then a little potted history of ice-skating, and I learned that ice skates were used as early as 200CE. Fascinating. Furthermore, there are 145 separate pieces in a modern ice-skate and I now know how to make one, including alignment and balance, where the white plastic insole goes and why the sole of the boot is sanded for good adhesion. It's riveting stuff. We then had a little intermission while the mullah reminded us all that it was prayer-time, just before the really interesting part when we got to find out how the blade was attached to the carbon composite sole.
I wonder why I didn't turn over. Channel-hopping, I chanced upon Channel Two right in the middle of a detailed tutorial on industrial winemaking. It included how much yeast to use, how the grapes should be prepared and crushed, the fermentation temperature (17 degrees Celsius for white, 30 degrees for red), how long the fermentation process takes and how to remove particulate matter on completion. I learned how to test for sugar during the process, how to use a hygrometer to check for alcohol content plus the expected range, the benefits of corking and why green bottles are normally used.
