Who wants to see a lot of plastic beverage bottles get filled with pressurized air until they explode with a loud bang? I do, and so did Chris Notap, who decided to see what it would take to make a pop bottle pop. The pressure in a bottle of pop is about 50 psi, and the many different kinds of bottles Chris pumped full of air exploded at between 150 and 250 psi. The explosions were quite violent. Chris says the caps are designed to come off before the bottles can explode, which is a relief.
Experiment: can a pop bottle explode on the store shelf?
