Science brain teasers require understanding of the physical or biological world and the laws that govern it.Science
Aliens place you on the bottom center of a large cylindrical aquarium. Your hands and legs are tied together. The cylinder sits on a turntable, which is now turned off. Your captors are about to release you so that you will float to the surface to gasp for air as soon as possible. The captors ask you, "Do we turn the turntable on or leave it off before we release you?"
Answer
Keep the turntable off. You will take as much as ten times longer to make your ascent if the turntable is rotating at 33 and a third rpm. Pressure differences and friction will delay your rise in a fluid in circular motion.Hide Answer Show Answer

leave it up to them. if you open your mouth to answer you will drown. the question you are asked needs to have an answer you can nod or shake to!!
Well, if sadistic aliens like these exist, I think I would prefer to die.
Cliff: If you do not care, that is fine with me, but to announce to everyone as if saying that NOBODY cares it is a big problem. Do not go into the science category if you don't want Science.
I do not understand it!
whats this obsession with cruel aliens?
true about the drowning thing, but it never said in the teaser how fast you are going, it might not matter, but what if its goin slower or faster?
hey paranoid you haven't done one of these in a while I would like to see some more.
Yes, but if you go up too fast you might get the "bends".
I thought the turntable would propel you upward!
