In the name of science, distinguished actor and voice of God Morgan Freeman sucked on a helium balloon, turning his famously deep voice high and squeaky for the Science Channel's Through the Wormhole.
Morgan Freeman's voice on helium doesn't actually have anything to do with the gravity study he's describing here, but the producers definitely applied the scientific method to this scene. (Hypothesis: You know what would be totally sweet? Morgan Freeman on helium. Procedure: Give Morgan Freeman helium and some lines to read. Conclusion: That was totally sweet.)
Through the Wormhole returns June 4. Morgan Freeman never left.
