In the 1989 sequel "Back to the Future 2", the heroes travel into the oh-so-distant future of 2015. Since that's only half a year away, you're probably wondering why some of the cool stuff they predicted still isn't in our hands.
Well, here are five that may be on the verge of coming true . . .
Vertical Takeoff and Landing Cars: The military is actually working on one, although it's not technically a car. It's a drone with heavy lifting capabilities that could carry and detach cargo like vehicles and pods full of supplies.
Mr. Fusion: We'll probably never be able to just throw random trash into a tank and have it run our vehicles. But there's such a thing as biogas, which is created from the breakdown of biodegradable materials. Cars that run on it probably aren't too far off.
Commonplace Biometrics: In the movie, people use their thumbprints just about everywhere, to do things like pay for stuff and open doors. In real life, the technology is here, it just isn't secure enough. It may not be common practice by the end of 2015, but if the technology improves, it could be the way of the future.
Weird TVs: In the movie, they have display screens you can roll up like a piece of paper, multi-screen TVs and TVs with weird shapes.
In the real world, there are already flexible displays on phones, and new technology allows TV companies to make a TV or display in any shape they want.
Hoverboards: Sadly, this one actually DOESN'T seem likely to become a reality anytime soon, so we're not really sure why it's on the list.
In 2010, a French artist named Nils Guadagnin built a replica of the hoverboard, and actually made it hover. But he used MAGNETS. It couldn't move OR bear weight.
