A bowling ball and a bag of potato chips are dropped at the same time from a tall tower on Earth. What happens?

The Bowling ball will hit the ground fist not because it has more mass but because it is less affected by wind resistance [resistance to its movement through the air] If the effect of wind resistance where [somehow] negated they would hit the ground at the same time.

[The bag of potato chips: Open or closed? Assumed closed for this answer]
