The science is ironclad: Tom Brady is a cheater, according to a 10-year-old’s fair-winning project.

Ace Davis, who attends Millcreek Elementary in Lexington, Ky., wanted to do something different for his experiment.

With the help of his mom and his sister, Davis set out to prove Brady and the New England Patriots cheated by conspiring to deflate footballs during the AFC Championship in the 2014-15 season.

Hypothesizing that “under-inflated footballs provide a competitive advantage in a game,” the Davis family took turns throwing footballs at different PSI — measuring for distance and accuracy.

His father, Christopher Davis, posted the results on Facebook, and they weren’t flattering for the Patriots’ franchise quarterback.

“The Patriots were found guilty of doctoring football [sic], thus losing $1,000,000 and future draft picks. Tom Brady is indeed a cheater,” Davis concluded with the help of graphs and charts.

It impressed the judges, who handed him a win in the elementary school fair, Christopher said in the post.

Davis isn’t a fan of Brady and wasn’t shy about wading into the Deflategate controversy.

“I hate Tom Brady, he’s been accused of cheating before, I want him to be caught,” Davis told NFL Draft Diamonds.

And when asked what he would tell Brady if he could share a message with him, Davis said, “Gimme some of your money, you don’t deserve it.”

The NFL suspended Brady for the first four games of the 2016 NFL season.

The elementary-schooler has moved on to the district-level science fair and seems pretty confident.

“Yep and I’m gonna win that, too,” he told NFL Draft Diamonds.
