The Science Behind “Deflate-Gate”
The Pressure In AFC Championship Footballs Could Have Changed By 1.95 PSI From
Weather and Field Conditions
Pittsburgh, PA (January 23, 2015) -- HeadSmart™Labs, a Healy Ventures LLC company, today
announced findings from a study on football inflation levels in different climates. The study indicated
that the pressure in the footballs used in the AFC Championship game could have dropped 1.95 PSI
from weather and field conditions alone.
HeadSmart Labs set out to discover if weather during the AFC Championship Game on Sunday,
January 18 could have affected the inflation levels in the footballs. The Lab designed a study that would
simulate the external elements the game footballs were exposed to. The study encompasses the
timeframe from when referees would have initially tested the footballs prior to the start of the game, to
the time when the footballs were found to have a lower air pressure during halftime. Reports state that
when the game officials tested the New England Patriots’ footballs during halftime, 11 of the 12 were
found to have lost pressure of about 2 PSI.
“We took 12 brand new authentic NFL footballs and exposed them to the different elements they would
have experienced throughout the game.” said Thomas Healy, founder of HeadSmart Labs. “Out of the
twelve footballs we tested, we found that on average, footballs dropped 1.8 PSI when being exposed to
dropping temperatures and wet conditions.”
During testing, twelve brand new footballs were inflated to 12.5 PSI in a 75 degree Fahrenheit room.
This was to imitate the indoor conditions where the referees would have tested the footballs 2 hours
and 15 minutes before kickoff. The footballs were then moved to a 50 degree Fahrenheit environment
to simulate the temperatures that were experienced throughout the game. In addition, the footballs
were dampened to replicate the rainy conditions.
