The Leidenfrost effect is a phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer which keeps that liquid from boiling rapidly.
Thanks Wikipedia.
So these people use specially-crafted surfaces at 200 deg C to direct water in a controlled manner.

Next on list: Do something similar for superfluids. 😉
amazing science! thanks for the share
Awesome!
ah-mazing!
superb
You can try this at home with a really hot frying pan and water!
That is very cool. Thanks for sharing.
cool
Awesome!
AWESOME
Brill! I've observed this effect on a hotplate before but never given it any thought. This is amazing – like science meets mysticism. Explain that without sounding wacky!
the water drops are like "its hot, its hot, its hot" as they try to keep their feet from touching the ground and run away from the hot suface 🙂
Mythbusters did this with molten lead and their fingers. Definitely would NOT try this at home with a very hot frying pan and water!
Why? The worst thing that can happen is it's not hot enough and makes steam and it's not like you use enough to scald you so?
Ok. Fair enough. But I'll let you do it 🙂
Dip your hand in molten lead without being burnt!
There is no way i'd have the balls to do that!
Interesting.
SO does it provide any mechanical energy?
WOWÂ This phenomenon would have many applications
Super cool!
Absolutely fascinating…
ok….
