Or perhaps because it's easier to scrape down the sides of a rounded container with a spoon?...

This year’s award winning film: The Shape of Soup.

I disagree hard. The shape of soup is temperature based.

Soup cans > soup cubes

I was wondering why they make them in cans rather than cubes since it’s space lost and found this:

The cylindrical shapes of cans are a major benefit when manufacturing products. The cylindrical shape is the perfect cross-section of using the least amount of material but being able to fit the most product into shipment boxes and on store shelves. A spherical shape is inefficient for packaging, and a cubical shape is inefficient in terms of material use. The cylindrical shape is just right by using a rounded top (like a sphere) and elongated sides (like a cube). This cylindrical shape is also critical for withstanding pressure. This shape can withstand up to 90 lbs of pressure, making them a durable product for day-to-day life.

Bouba shaped soup

The better version of this joke

Assuming no gravity, soup is a sphere.

well rounded logic

I wish bouillon cubes were spheres

Because you can't explain. Because your brain is in a round container and it has personal biases in shape preferences.

I agree. A liquid should have the freedom to expand in all directions equally.

Everything else is just needless abusive or cruel behavior towards soup.

It's very hard to get all of the soup out of a square container, because a spoon won't reach into the edges properly

yeah, ok. tend to agree. although i will allow a Squircle

I prefer square because it's easier to fold the soup.

"How to fold soup" Steve Martin, Cruel Shoes.

Nah, its because you need to scrape down the sides to get all the soup at the end and if its a square container you can't do that in the corners. Round containers are just easier to scrape down.

Here some soups are sold in Tertrapak cartons which I suspect would break the average American.

Of course not - no explanation is necessary!!

I don't even possess a round container. They're strictly less practical than rectangular ones

Soup is round Soup cans are Soup cubes We must resolve this tension Soup cobes

Never trust soup from a tetrapack

Ha ha ha. It's true, soup is round, was there ever any doubt?

For those that need an explanation: round containers don't have corners, but square ones do. Soup is a liquid, which means it will occupy the corner. The corners are very difficult to get liquid out of; be it with a spoon or otherwise for eating, cleaning, serving, etc.. Putting soup in round containers keeps that problem from occurring.

I currently have a square glass container with chowder in it on the top shelf of my fridge. Does that count as soup, stew, or is chowder its own category?
