On a recent episode of Jimmy Kimmel (see original clip above) I used a soda bottle to demonstrate a build up of gas pressure. Typical soda bottles are under about 40-60 PSI (pounds per square inch) of pressure when they are bottled. But they are designed to withstand much more pressure – usually around 150 […]
