frLa bière se déguste mieux au Pub!
enA: Hey C, what are you up to?
C: I'm inventing powdered beer, so that it is easier to carry on camping trips. I freeze-dried some beer, added a pinch of an endothermic catalyst... Then all we need to do is to re-hydrate with water and ethanol, and ta-da: Instant cold beer! Do you want to taste?
A: Uhmm, no thanks! It doesn't look very tasty...
