The walls of not one but two buildings came tumbling down in Springfield, Illinois on Wednesday.

After an implosion knocks one structure down, the other was supposed to implode seconds later, but nothing happened.

Crews kept working at it, but that structure didn't implode until it was good and ready.

The 45-year-old building finally came down eight hours later.
