OK, one the simplest of questions, can the Flash run or walk on water?

The reason I ask is because no matter how fast he can move, he needs something to push against.

I am assuming that he can as hitting water at great speeds gives it the property of concrete so to speak. But I want to know if he has done it?

    I admit to not having watched much of the new show, but wasn't there some silliness where he was running up the inside of a cyclone cloud or somesuch? – Radhil Apr 27 '17 at 12:43

    You had the extended universe tag, but that universe hadn't actually had any meaningful runs by Flash. Assuming any universe, here's a video from the TV series; the number of water runs in comics is probably uncountable, as it's a pretty minor feat for a speedster. – Gallifreyan Apr 27 '17 at 12:54
  • @Radhil, I have not seen any of the new show, so I don't know??? – KyloRen Apr 27 '17 at 12:55

    @Thunderforge Every Flash can run on water - otherwise they're just a glorified Usain Bolt (no offence meant to anyone) – Gallifreyan Apr 27 '17 at 16:25

    I voted to close, not because it's too broad, but because if you google "flash run on water" or several variations of that, it's literally the top results. We used to have a "no research done" reason for closing, but I guess that's gone now. – Omegacron Apr 27 '17 at 19:48

I'm not sure if he's ever been depicted as doing so in the current series. [EDIT: Yes he has, thanks to Gallifreyan] However, he was shown doing so in Ep1 of the 1990 series.

Regardless of whether he has been shown as doing so or not, it is extremely likely that he can based on real world physics and examples. The Basicliscus Lizard can run on water

...at a velocity of 1.5 meters (4.9 feet) per second for approximately 4.5 meters (15 feet)...

It is calculated here that to run on water you would have to run at approximately 30m/s, or around three times faster than Usain Bolt. Is the Flash more than three times faster than the Lightning Bolt? The Flash has been depicted as running at at least Mach 1 which is 343 m/s.

So yes, the Flash could run on water.

    Aren’t their some iterations of the Flash that can outrun light? – KRyan Apr 27 '17 at 17:40

    Several iterations of the flash have run much faster than light. See scifi.stackexchange.com/questions/5928/… – Bob G Apr 27 '17 at 18:26

    running too fast (not even getting remotely close to light) should put him in orbit pretty quickly (basically escape velocity + whatever is necessary to beat air resistance) – njzk2 Apr 27 '17 at 20:09

    @njzk2 The Speed Force is basically a "Get out of physics free" card for all of the logical flaws with super speed, though; it canonically makes speedsters immune to, for example, bursting into flames from the friction, among other things. So, it likely includes a super-anchoring effect to keep them from catapulting off into the void. – Justin Time - Reinstate Monica Apr 27 '17 at 21:20

    @JustinTime How dare you link to something other than the relevant XKCD What If when talking about friction vs. a relativistic speed item. – jpmc26 Apr 28 '17 at 9:33

Yes, the Flash can run on water, much like the common basilisk.

I can't speak for the comics, but in the TV series it first happened in S1E5:

    Wait, is he setting the water on fire as he runs? – mattdm Apr 27 '17 at 14:13

    @mattdm, don't think so -- it appears to be the standard snap/crackle/pop as he runs – bedwyr Apr 27 '17 at 15:06

    This QA is proof that this site is the best site in the SO network :) – Fattie Apr 27 '17 at 18:03

Yes, on Superman Vol 1 199 The Flash races around the globe against Superman, as you can see he is able to run over water
