Taking down the five-story building is a bit more sophisticated than toppling over a tower of blocks, but the concept is the same.
"I figure [my daughter] is at the stage where she likes to knock things down. She's going to enjoy this after it scares her!" parent Tony Schwietzer said.
Some have a curious fascination that keeps them wanting to watch the tumbling of a building over and over again. If you blinked during the demolition, you missed it. However most of downtown heard its roar.
As for the after shock, those in the downtown area who didn't know it was coming seemed to experience the most shock.
One viewer wrote to 9NEWS saying, "Explosion! At 8:00 today, there was a large boom, and a concussion wave that hit the second after."
The sound was even startling to those who planned the demolition.
"Well, it was a little louder than I thought, but it went as planned," Project Manager Bill Mosher with Trammell Crow Company said.
He says it was time for the building to come down.
"[Buildings back then] just weren't very well constructed; lots of leakage issues, water issues, lack of quality materials," Mosher said of the 33-year-old building.
Mosher does promise that its replacement will last longer. Maybe one day, the little guys that witnessed today's demolition will take their grandkids to see the phenomenon all over again.
Construction for the new $258 million judicial complex has already started at 14th Avenue and Broadway. It is going to be 600,000 square feet, and will house the Colorado Supreme Court, the Colorado Court of Appeals, and the Colorado Attorney General's Office, along with a number of other agencies.
The complex should be finished in the spring of 2013.
