Every once in a while I see a piece of technology that seems so implausible that it couldn’t possibly exist, yet it does. This robot arm with a Teflon sheet attached is just such a piece of tech. It’s so slick that it can pick up a splash of semi-liquids like ketchup or mayonnaise without even changing the shape of the puddle.

The uses for the SWITL, as it’s called, seem pretty widespread, with the company behind it envisioning applications in packaging delicate materials like meat as one option. All I know is that I’ve watched it several times and I still cant believe how smooth it works and how the ‘gel’ materials stay in the same organic shape. It’s truly remarkable.
