As we wait for the production of hoverboards and self-lacing shoes, we bide our time with Pepsi Perfect. The soda that Marty McFly orders from an '80s-themed diner will be available October 21 to coincide with the date he travels to in Back to the Future Part II.

The movie might have been wrong about hoverboards, but they at least nailed the themed diner (yes, they exist). Unfortunately, no diners will be selling these unusual bottles: The expensive collector's items are only being sold online in collectible cases. The limited supply means there will only be 6500 up for grabs. 

If the $20.15 price tag seem a little steep for an otherwise unremarkable bottle of pop, you can also try your hand at getting one for free. The first 200 Marty McFly cosplayers to arrive at New York Comic Con, which runs from October 8 to 11 this year, can get their bottles at no cost. This might be enough motivation to dust off your old puffy jacket and blue jeans.
