You’re missing the point with the sword, I think. The point was to catch it with your bare hands, using your palms. THAT is what they tested for, and that is what they busted.

No, sorry, Sandra. No human can run that fast. I’ll try to explain why.

To avoid sinking, you need to generate thrust equal to your weight by pushing water down and backwards with each step. If you had a size 9 shoe, you can’t push more than around 3.5 liters (0.92 US gallons) of water at a time or you would sink too far and friction with the water would slow you down too much. So you have to push that much water FAST enough to offset your weight.

If you weigh 75 kilograms (about 165 pounds), you’d need to push the water back at about 11 meters per second (or a little over 24 miles per hour). Since the water pushes back, you actually need to go at least twice as that, or you would stand still.

That means you’d have to run about 80 kilometers per hour (almost 50 miles per hour), which is impossible even in my simplified explanation which ignores things like fluid drag.

A myth-understanding (pun intended) of the Mizo Gumo by Adam and/or the research team?

What they missed is that ANYONE can walk on water, and the only equipment you need is… water, and a solid floor.

Fill a glass with water. Pour it on a tile floor. Now start walking. Congratulations… you’re walking on water! ;-)

You can walk on water with buckets tied to your feet or foam. Ninjas easily could have used buckets. You can catch arrows if you close your hand before the arrows is fired. Swords can be stopped easily with iron gauntlets. Mythbusters suck.

In the 1960′s my husband walked across pools, ponds and lakes using a commercial product called Water Shoes. They were large fiberglass covered foam with plastic flaps on the bottom. We still have them and he still uses them.

These guys are not ninjas. I don’t see how they can count these tests as valid. Classic ninjas spent their entire lives training, so these tests are anything but scientific.
