If, however, you drop them in a gas, the xt will fall "faster" because it has a smaller surface area and hence less total drag force due to interaction with the gas.
edit: I will perform this benchmark if any of you would send me these cards.
rancor said:Depends on how the cards fall though, if one is on its edge and the other on the flat side.

yevaud said:You are right. I would need to perform the test at least 20 times to be able to develop a statistically significant result. I can provide the stopwatch, the pen, and the ten story drop. Need volunteers on the cards.
