20 Mind-Blowing Facts You Didn't Know About The Flash

8. He Uses A Treadmill To Travel Through Time

If The Flash runs fast enough, he's able to travel through time. However, the hero doesn't have a lot of control over where he'll end up that way, so he created a unique and very strange solution to tackle this problem. The Cosmic Treadmill (which as you might have guessed, is powered by cosmic rays) allows the speedster using it to travel to a very specific point in time. It's a pretty goofy idea, but the device played a key role in a number of stories until Wally West developed the ability to precisely travel through time. The Flash's TV series has shown Barry running on a treadmill, undoubtedly an Easter Egg to this comic creation.
