Jack and the Bean Stalk flux capacitor Easter Egg - Jack and the Bean Stalk Flux Capacitor

While watching Jack and the Bean Stalk (2010), around minute 6 Christopher Lloyd plays a teacher for Jack. On the black board behind him and the right hand side there is a flux capacitor (from Back to the Future). This is significant to Lloyd as his character in Back to the Future invented the flux capacitor for time travel. On the left side of the board, 1.21 gigawatts is written, which is another reference to the flux capacitor. It was the amount of energy need to power it for time travel.
