I remember when I first that Hoverboard in Back to the Future II, I wanted one so badly! Every kid did! I was in elementary school when the movie came out, and I remember going to school excitedly talking with my friends about how I was going to talk my parents into buying me one. I didn't know about how special effects in movies worked back in the day, I thought they created an actual hoverboard for the film! So yeah, I thought it was real! I was so pissed when my parents told me otherwise, how could that be? I saw it work on screen flawlessly with my own two eyes! How dare they tell me it didn't really exist. Well, it does now, and yes... I still want to live out my childhood dream of owning one.
French artist Nils Guadagnin went out and created a replica of the popular hoverboard from the film, and it actually hovers! Here is an explanation of what type of magic was used to pull it off.
Integrated into the board and the plinth is an electromagnetic system which levitates the board. A laser system stabilises the object in the air.
Wait a second... a laser stabilizing system!? What type of alien technology are we looking at here? Check out some more pics and a video of the board below.
