8. Attractions at the New York State Pavilion Cost Around as Much as a Subway Ride

The 1965 Official Guide Book for the New York World’s Fair lists the various prices for admission into the New York State Pavilion: while access to the Tent of Tomorrow was free, adults had to pay 50 cents to visit the Observation Towers (and children, 25 cents).

When adjusted for inflation, a 50-cent admission fee costs about $3.94 today, and 25 cents is about $1.97. As an alternative to the Sky-Streak elevators, visitors could also pay $6.50 to take a helicopter tour that encircled the fairgrounds at 500 feet — that comes out to about $51.27 today (not too shabby for a helicopter ride).
