ELI5: How do those bladeless fans work?

It's Satan as far as I can tell.

The pedestal of the fan contains a brushless electric motor that takes in air and feeds it into the circular tube. Air flows along the inside of the device until it reaches a slit inside the tube. This provides the basic airflow that creates the breeze you'd feel if you stood in front of the fan. Dyson claims that the Air Multiplier generates a breeze with 15 times more air than what the device actually takes in.

There **are** blades in the fan -- you just can't see them. The pedestal hides the blades. A motor rotates nine asymmetrically aligned blades to pull air into the device. According to Dyson, these blades can pull in up to 5.28 gallons (about 20 liters) of air per second.
