Sounds like a bomb going off! Nuts!

Residents and businesses in Crocker Park, Ohio were alarmed when they saw flames violently bursting from a nearby propane tank. Luckily, rescue officials evacuated everyone from nearby buildings before the tank exploded and damaged buildings caught in its blast radius. No injuries were reported near the incident.
