Flux Capacitor

Flux Capacitor
To build a time machine, you need these things: a small nuclear reactor, a cool car that easily does 140 km/h, and of course a flux capacitor. A time jump requires 1.21 gigawatt of power –which is no problem for the reactor in the back that runs on plutonium or optionally garbage ;).
As a Back to the Future fan, you already knew all this, right? So, like us, you're no doubt still waiting for all the inventions, like the hoverboard, that should have been ready for mass production in 2015!
Well, at least you don't need to wait for this shirt! Plus, we understand that you won't only want to wear it in the 1980s… so choose from different colours and sizes everywhere –in: 1885, 1955, 1985 and even this year!
