If the container's not airtight then the gas has a place to go safely. If the container is airtight, the gas just builds until the container bursts. This is only fun when watching it on Mythbusters as it is quite destructive. Geeze, am I giving 'terrorist' lessons here?
Nah... a few genius theater techs though it would be funny to set one of those off in the empty house (as in theater house, where the seats are in a theater, ours are removable, and we only put the seats in on show weekends) during a cast party after strike in the Playhouse. They had left over dry ice from a fog effect in the show... they used just a little in a 20 ounce soda bottle... and at the last minute, being engineers, realized just how fast the plastic shrapnel was going to be going, and decided it was a bad idea. So they picked it up and ran it to the stainless steel sink in the set shop... one of those square, not embedded in any kind of counter industrial looking things.
When the bottle went off... it cracked the sink.
They had a bit fo a time explain to the executive committee why they needed to buy a new sink for the setshop.
