The latest advances in science can help us do amazing things — like fly pilot-less airplanes, send spaceships to Mars and design smaller, and even more powerful, computers.

But go to your refrigerator and you can find a more mundane challenge that modern science has also tackled: how to get those last drops of ketchup out of the bottle.

It's called LiquiGlide — and you might have seen the video of it that went viral.

When applied to the inside of a bottle, it allows ketchup or mayonnaise or mustard, or even toothpaste, to slide right out. No shaking or squeezing — just tilt and let gravity do it's thing.

  • "That, in essence, is LiquiGlide’s product. The process involves spraying two separate materials to the inside wall of the container: The first, a solid material, traps the second, a liquid material, creating what Smith calls a “permanently wet” layer against which the product can easily slide."
