just some random thought, the microwave oven lets you cook stuff like it a couple of seconds. that's by vibration of molecules...that's heating up stuff. but what about cooling down stuff? like if i have some drink and i want to cool it down...i know i could put it in the fridge, but it takes almost forever (forever being around an hour) relative to the temperature change a microwave oven can do in that kind of time (probably if i put something in the microwave for like an hour it would just vapourize lah). yesh...just wondering...back to circutis
