A Real Thor Hammer That Is Impossible To Lift

One of the most memorable scenes of this summer's Avengers: Age of Ultron is during a party at Avengers Tower, where Earth's Mightiest Heroes all try to wield Thor's hammer Mjolnir, to no avail. The brilliant minds at Sufficiently Advanced have created their own version of Mjolnir, that literally only one person on Earth can wield. The hammer is actually constructed with an electromagnet from a microwave oven, which is connected to a thumbprint scanner on the handle, which only recognizes the thumbprint of the creator. Therefore, when placed over a metal surface, no one is able to lift this hammer. Make sure you watch until the end, to see how one guy managed to beat the system.

Tom Hanks Acts Out Bridge of Spies Scenes Written By Kids

Before critically-acclaimed drama Bridge of Spies hits theaters this weekend, Tom Hanks stopped by The Tonight Show Starring Jimmy Fallon, where he acted out scenes written by children, as part of a segment known as Kid Theater.

The Walking Dead Protein Bar Mystery

In last week's Season 6 premiere of The Walking Dead, one of the most memorable scenes was a callback to the Season 3 episode Clear, where Rick (Andrew Lincoln) reunites with his old friend Morgan (Lennie James), along with Michonne (Danai Gurira). Michonne is seen eating some of Morgan's food, which she justifies with the line "The mat said Welcome," a scene that is brought up during last week's episode, when Morgan asks Michonne if she ate one of his peanut butter protein bars. Michonne says she didn't, but Cyber Cat Films has put both scenes together in one video. While Michonne is certainly eating something, we don't know for sure if it's a protein bar. Could Rick have been the one to steal Morgan's last peanut butter protein bar? Perhaps this mystery will be solved later on in the season.
