A bullet train for your mobile phone
You can add as many cars as you want to this strap.
We've never quite understood the concept of phone straps, much less some of theoften attached to them. (Well, perhaps there are one or two .)
But the "Super Shinkansen Bullet Train" could change our minds about the whole trend. It must have something to do with our first ride on them, a childhood rail trip that was the closest we've ever gotten to one of those human centrifuge machines that makes your head feel like exploding.
We wouldn't advise spinning your phone around lariat-style to get that kind of rush. But, as Gizmodo says, you can still play engineer by adding as many cars as you want, connecting them with middle cars that snap together for an extra charge.
