I'm scanning my brain inside a plane that’s about to DIVE toward the ground… to test how weightlessness helps or hurts your brain. And it’s just one of the 5 crazy science experiments I got to test inside a Zero G plane. I recently went on this Zero G plane to explain a big debate about gravity, and while I was there, I also got exclusive access to experiments that can ONLY happen in zero gravity. I just knew you’d love to see it.
