We all recognize Morgan Freeman’s beautiful, deep voice. But how does it sound when a little bit of helium is added to the mix? Thanks to Science Channel’s “Through the Wormhole” series and a promo video for its Season 5 return, we have the answer.

It sounds amazing.

Why is Freeman, an Oscar-winning actor and American-movie icon, sucking on a red helium balloon? The reason seems to be equal parts science and silliness. Ostensibly, Freeman is demonstrating how things get weird when black holes are involved. But mostly it’s an excuse to listen to a high-pitched version of Freeman’s famous voice.

Does this have more of a connection to black holes than it seems? We will probably have to wait until the Wednesday, June 4 premiere of “Through the Wormhole” Season 5.
