eli5 why does it make a loud bang when you pop a plastic bag or bubble wrap?
In: 2
not a physicist but it’s probably as simple as you’d think it is. lots of pressure built up to the point where it simultaneously ruptures the material and releases all that pressure. not sure if that’d make it fall under the technical category of an explosion per se, since theres no real chemical reactions happening here, but it’s similar to why a gunshot is so loud. lots of pressure being released at once.
