Cup of Coffee
Science brain teasers require understanding of the physical or biological world and the laws that govern it.
You are served a hot cup of coffee and room-temperature cream at a restaurant. You want to wait a few minutes before you drink the coffee, and you want it to be as hot as possible when you drink it. Should you pour the cream in the coffee:
a) Immediately
b) Just before you drink it
c) It doesn't matter
( "don't add any cream" is not an option)
