i saw a comment about tipping a fedora 40,000 times a minute so i did some math if the average fedora tip causes the brim of the hat to move from resting, to just below your brow, to back, covering 5 inches, you would be tipping at 277.77 miles per hour the front brim of the fedora is about 8 sq. inches, so one tip would displace 40 cubic inches of air, moving 11111.11 cubic feet of air per minute, enough to almost entirely aerate a 1500 sq. foot home with an 8 foot ceiling
