Do you want to find out how to get ketchup out of the bottle without a big gush?
Then let’s take a closer look at the red sauce and examine its properties.
Ketchup is a liquid, like water or oil. To get to the bottom of its secret, we should therefore take a closer look at the properties of liquids.

Until then, you can tell Steffie and the others in the community which dish you cannot do without ketchup.
