There's an interesting discussion around a mystery involving cans of Ocean Spray cranberry sauce. Some eagle-eyed TikTok users have noticed that the labels on the cans are always upside-down. The rounded edge of the can is at the top of the label, which is confusing a lot of people.
But there is a perfectly good explanation for it -- and it's all about science. The top of the can, which actually looks like the bottom, contains an air bubble inside that helps to push the cranberry sauce out of the can when it's opened. Without an assist from the air bubble, the cranberry sauce wouldn't slide out cleanly and keep its can-shaped form.
