Everything You Need to Celebrate Back to the Future Day

This is How You Do Back to The Future Day: Start With a Hoverboard

In 2012, Mattel manufactured a limited number of hoverboards as special collector's items. They're still available for purchase on Amazon, but be prepared to pay a sizable premium on the original $120 price. And before you ask, no -- it doesn't actually hover. We're disappointed about that, too. (Photo by: NBC Universal)

Fly on a Real, Working Hoverboard

Okay, okay, we hear you -- nothing short of the real hoverboard deal will do. The folks at Hendo Hover have successfully Kickstarted their own working prototype of a levitating hoverboard. It uses magnets, so it only works over metal substrate. It also carries a hefty five-digit price tag. (Photo by: Hendo Hover)

Drink a Pepsi Perfect

No need to head to the 80s Cafe the next time you're thirsty for a bottle of Pepsi. Starting October 21, Pepsi will begin selling cola out of the same oddly-shaped “Pepsi Perfect” bottles seen in the movie.

The are some big catches, though: The drink is only being released in limited quantities, and each bottle will set you back about $20. You'll also need to pay close attention to Pepsi's social media pages -- it's where the company will announce how you can actually buy one. (Photo by: PepsiCo)

Put on a Multi-Colored Hat

Going hatless is so 1985. The best way to fit in with your fellow citizens of 2015 is to don a shimmering, multicolored, reflective hat, just like Marty. Fortunately, you can purchase your own replica of the Back to the Future II prop over at Think Geek for just $24.99. (Photo by: NBC Universal)

Build a Real-Life DeLorean Time Machine

Turn your run-of-the-mill stainless steel gullwing sports car into the time-traveling dream vehicle you've always wanted! Bob's Prop Shop in Dallas, Texas offers a full-service DeLorean prop kit that can turn any ordinary Delorean into an authentic-looking Back to the Future clone. The conversion costs a whopping $49,999; DeLorean (and plutonium) not included. (Photo by: Bob's Prop Shop)

...or Just Rent a Time Machine

If you don't have $50K (and a DeLorean) to spare, Bob's Prop Shop will also let you rent a modified DeLorean for the day. You'll pay $1,500 per day for the privilege, plus a $0.15-per-mile travel fee if you want it sent outside of Texas. Fortunately, that price includes a security detail for the vehicle, so you won't need to worry about Biff Tannen stealing it. (Photo by: Bob's Prop Shop)

Watch the Trailer for Jaws 19

In our world, Jaws: The Revenge (1987) was so terrible that it killed off the series. In Hill Valley circa 2015, however, the Jaws franchise is still going strong. To celebrate Back to the Future Day, Universal Pictures has created a hilarious trailer for the fictional Holomax movie Jaws 19 that you can watch right now on YouTube. (Photo by: NBC Universal)

Wear Marty's Jacket of the Future

In Back to the Future II, Marty McFly and his future son both wear automatically adjusting jackets that can dry themselves when wet. You won't find such a thing in our version of 2015, but you can find a decent-looking replica at HalloweenCostumes.com for $68.99. To complete the look, remember: In 2015, all the kids wear their pants pockets inside out. (Photo by: NBC Universal)

Wear a Pair of Nike Mag Sneakers

Marty's automatically lacing Nike Mag shoes may still be science fiction, but in 2011, the shoe company decided to manufacture and auction off a limited number of kicks inspired by the movie. The effort raised more than $5.6 million for charity, with most pairs selling for between $30,000 and $40,000 each. That's pretty expensive for sneakers you need to put on manually.

Or Save Some of That Money For ... the Future!

Don't have tens of thousands of dollars to drop on Nike Mags? You can still get your fill of futuristic 2015 style with these Universal Pictures-licensed replicas available via HalloweenCostumes.com. The shoes light up, just like in the movie (rechargeable via USB). They're lacking the Nike logo and trademark swoosh, but that missing detail drops the price of a pair all the way down to $98.99.

Embrace the Chicago Cubs' World Series Destiny

Not to spoil the future for you (sorry, Doc Brown), but according to Back to the Future II, 2015 is the year that the Chicago Cubs finally break their 107-year World Series losing streak. And indeed, the supposedly cursed team has made the post-season this year. We're slightly less bullish, however, on the movie's call that the Cubbies victory will be the result of a 5-game sweep over the Miami Spacers. (Photo by: NBC Universal)

Build a Lego DeLorean

If you love Back to the Future and Legos, prepare for your head to explode: The beloved toy brick maker has made an official DeLorean Lego kit, complete with mini Marty and Doc Brown figurines. Sadly, this Lego kit has been officially discontinued and is no longer available directly from Lego, but you can still find boxes in collectible shops and on Amazon at a markup. (Photo by: Lego)

Use a Funky DeLorean iPhone Case

This specialized Back to the Future DeLorean iPhone 6 case from Japan is one of the weirdest -- and coolest -- iPhone cases we've seen in a while. The case itself is a full 3D model of a DeLorean hovercar, complete with working lights. It sells for the U.S. equivalent of $50 in Japan; ordering it stateside from Amazon will cost you closer to $100. (Photo by: Bandai)

Grab a Copy of Grays Sports Almanac (for your iPad)

Any Back to the Future fan knows: Putting a copy of Grays Sports Almanac (1950-2000) in the hands of the wrong person could create a dystopian, casino-filled nightmarescape. Fortunately, this version of the almanac is just a case for your iPad Air, so it's been cleared for time travel. You can find yours on Firebox for $30.39, much cheaper than the $7,250 (U.S. equivalent) that the actual movie prop recently sold for. (WARNING: Do not send your iPad Air back in time.)

Install a Flux Capacitor

You don't need big bucks or a DeLorean to add a little bit of Back to the Future flair to your car. This light-up flux capacitor USB car charger will keep your smartphones and other gadgets charged on the go. You can find yours at Think Geek for $24.99. (Photo by: Think Geek)

Stream the Full Back to the Future Trilogy on Amazon for Free

Arguably, the best way to celebrate Back to the Future Day is to re-watch the series. Amazon Prime members can now stream all movies in the Back to the Future trilogy for free via Prime Instant Video. (Photo by: Corbis)

Play Jetpack Joyride's New Back to the Future Theme

To celebrate Back to the Future Day, popular mobile sidescroller Jetpack Joyride has added a brand-new mode where you can play as Marty McFly, Doc Brown or Biff Tannen, piloting your choice of hoverboard or DeLorean through 2015 Hill Valley. The app itself is free on iOS and Android; Amazon Underground users (Android) can enjoy free in-game purchases as well. (Photo by: Halfbrick Studios)
