Even if you blow softly, they start panicking and running all over the place

It’s called an Alarm response.
Basically, one or more of the ants you just blew on has broadcasted a message to all the surrounding ants: “Big thing is taking an interest in us”
This is usually a chemical they put into the air called a pheromone.

They have different pheromones for different threats and also different responses.

For most ant though, “big thing taking interest” would probably be looking to eat a lot of ants. So if the ants were close together, it could just scoop up a lot of ants.
So the ants spread apart to make that harder.

For different threats, the ants might bunch up or even attack as a group.
