Someone I didn't know, in Texas, made a dry ice device with a 3 liter bottle once... He was with a bunch of friends about twenty years ago. They had made a whole trunk load of 20oz and 2 liter bottle dry ice devices, so they only needed to add a little water and screw a lid on for action. He must have had a fun afternoon. Saving the 3 liter bottle for last, they decided to do it on an "abandoned" road and watch it.

He said it swelled up so large it looked like a cartoon. The bottle got to be over three feet tall and just kept going over about 10 minutes. There must have been an insane amount of pressure because even he was afraid to get anywhere even kind of close to it. Then, a car started coming towards them out of nowhere. He said the last thing he saw out the rear windshield, as they sped away, was a man getting out of that car to inspect the enormous soda bottle in the middle of the road. He hopes the man did not poke at it...
