"The silent GIF shows what appears to be three pylons jumping rope. But the camera shakes just as the middle one lands, which some viewers believe they can hear or feel."

Cool, but I didn't hear or feel anything :(

I didn't "literally" hear anything, but my brain sort of went "thump".

It surprises me, though, that the scientists feel stumped. In linguistics, this is a well-known phenomenon called the "McGurk Effect." Basically, your brain plays a role in what you "hear." Not hard to explain at all, since the brain is processing all of your senses.

Kinda what Jeff said.

I don't "literally" hear anything but every time the pylon lands I 'hear' a 'thump' in my head. It kinda feels like I'm hearing it and I can't watch the gif and not 'hear' it.

The "McGurk Effect" that Jeff describes is pretty fascinating. Here's a video that demonstrates it and it's pretty wild.
