Watch This Liquid Membrane Filter Let Big Stuff Through and Keep Small Stuff Out

This is absolutely amazing....

Science fiction is full of portals and membranes that separate people, universes, and dimensions. (Remember the fleshy ones in Stranger Things that led to the Upside Down?)
Sadly, space-time portals are relegated to the imagination. But a new type of membrane is perhaps equally as cool, and offers practical, real-world applications.
A team of researchers at Pennsylvania State University created a novel, self-healing membrane. Unlike a coffee filter, through which liquid percolates and grinds are contained, the membrane works in reverse by allowing larger particles to pass through, while keeping smaller ones at bay, and words really don’t do it justice.

The membrane was inspired by endocytosis, according to a paper published last month in Science. Endocytosis is the process by which cells envelop and transport molecules—giving researchers the idea for a self-healing solution that can be penetrated by particles without leaving a permanent hole.
During tests, the membrane contained a swarm of fruit flies, and sealed gas within a tube while letting other objects through (leading the team to suggest its potential for “odor control.”). It also blocked contaminants during a simulated surgery “without inhibiting visibility or in-film maneuverability,” the paper stated.
