00:00The next puzzle is a morning dilemma.

00:02This one is from the Department of Physics of Oxford University.

00:05So you're running late for work, but also craving a caffeine kick.

00:08You pour yourself a steaming cup of black coffee, but it's hot to handle.

00:12How can your cuppa cool down more effectively?

00:14You have two options.

00:15You can go all in, adding milk right away,

00:17and then patiently twiddle your thumbs for a few minutes before taking a sip.

00:20Or you can play it cool, letting your coffee sit for a few minutes

00:23and then swoop in with the milk just before that first sip.

00:30The winning ticket is the second option.

00:34Here's why.

00:35Your coffee starts off hotter than in Option 1 when you introduce the milk.

00:39The thing is, hotter things have a knack for cooling down faster,

00:42thanks to a bigger temperature gap with their surroundings.

00:45So in Option 2, your coffee is racing against time, cooling down at a quicker pace.

00:49Interestingly, both options result in the same amount of time needed to cool the drink down,

00:54but at different rates.
