After all those text-heavy posts this week, here is something that really fascinated me recently. I had an empty ketchup bottle lying in my sink when I strained some pasta. Some time later I picked up the bottle and noticed how the label was all wrinkly. So this is how much a ketchup bottle shrinks if you pour hot water over it:
