Today, 21 October 2015 is Back to the Future Day.
It's the exact date that Marty McFly and Doc Brown arrive in the future, in the second 'Back to the Future' film, released in 1989.
The movie imagined a 2015 with hoverboards, flying cars, and self-tying shoes.
While some of the inventions have come true, lots of them seem pretty old-fashioned.
But what do kids growing up in 2015 think of the film's 'future'?
