Silly Kelly. You don't need a lightning bolt. Just a little bit of plutonium, which you should probably be able to pick up in any corner drug store. Or, for the flux capacitor 2.0, just feed some garbage to the Mr. Fusion add-on generator.
Thanks for the tip, I'm out the door now. I'm always running out of the stuff so I should probably just go to Costco and get the Kirkland family size box of it. Besides, the last time my neighbor came over and asked if he could borrow a cup of plutonium I was of no help to him because I had just used my last cup in the muffins I was baking.
