What Does It Actually Take To Shatter Glass With Sound? | MythBusters

In this episode of MythBusters, the team investigates whether a sonic boom can shatter glass, ultimately discovering that while a sonic boom can break glass under specific conditions, the myth that any sonic boom will break any glass is busted. The experiments reveal that the glass remained intact unless subjected to extremely low-altitude passes from a supersonic jet.

What Does It Actually Take To Shatter Glass With Sound? | MythBusters

Key takeaways

Sonic booms can break glass under specific conditions, but the myth that any sonic boom can break any glass is busted.
The Blue Angels provided a unique opportunity for the MythBusters team to explore the effects of sonic booms from supersonic jets.
The experiments showed that a bullet's sonic boom did not break glass unless the bullet made direct contact, emphasizing that impact is necessary for damage.
Sound travels at 761 mph at sea level, while a bullet can reach speeds of about 1984 mph, creating a shock wave that was tested against glass.
The team performed multiple tests with varying distances to determine how close a sonic boom needed to be to break glass, ultimately finding no significant effect at safe distances.
Research the conditions under which sonic booms can affect materials, focusing on distance and material type.

The digest

This exploration examines the popular claim that any sonic boom can break glass, using supersonic jets and high-powered firearms to test how sonic shock waves interact with different types of glass. The findings clarify the conditions under which such breakage occurs, dispelling oversimplified assumptions.

High-Level Overview

The experiment investigates whether the shock waves produced by sonic booms universally cause glass to shatter. Sonic booms occur when an object moves faster than the speed of sound, generating intense pressure waves. Popular belief and myths often suggest that any sonic boom can break glass, but this demonstration by MythBusters probes the limits of that claim. Through tests involving supersonic bullets and supersonic jets, the investigation finds that while sonic booms can break glass, it requires specific conditions not commonly experienced in everyday life. This matters for aviation enthusiasts, engineers, and those curious about physics in real-world phenomena.
