A lot of work went into making this and a thought it would go great with my doc and marty figures so this is how I made it. The body is made out of cardboard plus I made the doors open with Lego connecter pieces and the windows are made of clear packing tape plus the steering wheel is made out of Lego pieces, the time circuits and flux capacitor are made out of cardboard I just painted on the details. Next I made the back pieces out of cardboard wire from some ears buds and random stuff that matches how it looked in the movies plus and the plutonium chamber out of a Lego tire. The last thing I did was I made the tires out of Lego tires and that's it where we're going we don't need roads.
