Enough Molotov cocktails and it would get very hot.
For every can, there is an opener.
Long ago, before “American Graffiti” I knew of some guys that got carried away with a bit of a prank. The were all good boys from good homes and they aspired to be scientist, doctors and one wanted to be a US Senator.
They attached a steel cable to the rear axle of a parked police car and a very solid post.
20 MPH? (~30 FPS) at 3500lb.Thats enough energy to do some damage.
Some of this bunch still have an old newspaper article with a photo about this event.
