Can you autists explain the following phenomenon:
If I put water in my stainless pan and place it on a stove under medium fire (I usually do that to get rid of moisture at the bottom after washing it), it begins to heat up, but sometimes the water does not boil. The pan continutes to heat up yet the water is perfectly still, BUT, if I simply shake the pan lightly, the water instantly beings to bubble up. Why does that happen?
