This is a video from Insider detailing the duct tape manufacturing process (which apparently starts with a penis-shaped glue mound), and what makes the tape so strong. SPOILER: Ducks. Lots and lots of ducks. “Did you even watch it?” I didn’t need to.

Duct tapes were first invented by a female factory worker during World War II. They were originally called ‘duck’ tape because it was made out of a cotton duck fabric and it repelled water like a duck’s back.

What did I tell you? “Not that.” Similar though. “Not really.” Call it a toss-up? “You were wrong.” I’ve only been wrong once in my life and her name was Lydia. “Wait, what?” She ruined me.

Keep going for the video.
