Metal that Floats

My metal boat floats.. All 3 of them..

 

Fiberglass rides better... Doesn't break ice as well though.

 

Aircraft carriers are made of steel alloys - and they float - most of the time.

 

You can float metal on metal too.

 

Pane glass is floated on molten metal as it cools.

 

I guess that is what you get for trying to show people something new. Shaking my head.

 

Perhaps you just missed the humor, Baby, "It’s Etched With a Fricking Laser"

Besides, I could do the same thing with two sheets of aluminum foil and some masking tape, lol. Nothing really earth shattering here, they basically hollowed out two pieces of metal & then stuck them together and it floated.

 

That's not what they did. The used laser ablation to create a surface on the metal that trapped air molecules and essentially gave the metal buoyancy

 

Hmmmm, weapon or salvage application?

 

Article ,as I recall, never stated how thick the metal was or how deep the engraving was. Sounded a little sketchy to me too.
Don’t know how physics works on that unless the honeycomb it almost thru with very fine ribbing

Ever learn to float a metal paper clip on water in science class?

 

Armored personal carriers float and they're made out of metal.

 

Flour gold floats too.

Creating floating metal with a fricking laser sounds like an expensive process, for what purpose?
Metal surfboards?
Floating anchors?lol!!

 

And a magnetized needle to make a working compass.
