Engineers use gravity to collapse massive bridges in just a few seconds
Modern engineers utilize the power of gravity and precisely timed explosives to bring down massive, thousands-of-ton bridges in a matter of seconds through controlled pancake collapses.
Controlled bridge demolitions use high-precision explosives to cut through key supports, allowing gravity to do the heavy lifting. By timing blasts to within 1/1000th of a second, engineers trigger a pancake failure that can collapse a massive structure at speeds exceeding 100 kilometers per hour.
