Chicago Firefighters used a new tool for the first time on Monday fighting a large fire on the north side of the city.
It's a "High Expansion Foam" truck - that can create hundreds of thousands of cubic feet of foam in a very short time.
Firefighters here have used foam before, bringing in special trucks from O'Hare and Midway to fight structure fires, but the new truck is deigned to be used in the city, not at an airport.
The situation it created drew a huge crowd, as people tried to figure out what all the white stuff was.
Some thought it was snow, but with temperatures in the 60s, that obviously wasn't the case.
You can see how the foam covered everything in sight, and created a more playful environment than you'd ususally see at a fire scene.
Chicago Fire Officials say you can expect to see the foam truck more often, as they plan to use it whenever it's an "appropriate firefighting tactic".
