i thought ice was going to be just like, freally straight for id no, it's not. Ice is slippery for lots of different reasons. And one thing i've found, and perhaps lots of your listeners already know this, is that ice isn't always slippery. But what's interesting is, as the temperature of ice increases, the friction that exists between a steel blade,. or, in the case of the experiment that i am kind of alluding to, was a steel ball being dragged along ice at different temperatures. Soa minus 100 degrees c, friction is very high. As the temperature increases and gets closer to zero degrees s, friction decreases pretty steadily. It reaches
