Superfluid film

Superfluid film is a special kind of liquid that behaves like a very thin film or sheet. It's so thin that it can be spread out in a very thin layer, almost like a sheet of paper. Superfluid film has some really cool properties, like it can move without friction and it's able to flow up the sides of a container without spilling over. It's so slippery it can even make things float in the air! It's made up of tiny particles that are so close together that they act like one big piece.
