Soda can might explode: help!

  1. I joined this group specifically because of this q. I came home and found a can of Sierra Mist at the back of my fridge, in a uniquely expanded orientation. It looks like a double ended bullet.
    Of course, I realized what was happening, the thing froze, and I delicately placed it into my stainless steel sink, hoping it has done its worst.
    Help! Is there something I need to do to dispose or dispel this safely?!?!

    It's not dangerous. If you're really concerned, set it a fair distance away and shoot it.
     
  4. Stick a fork in it.

    If the can froze without bursting, just put it into some tap water until the contents have melted. Remember, water expands when it freezes, so the extra volume of the ice should vanish when the contents return to a liquid state.
     
  6. Sigh * of relief. Thank you!
     
  7. Because its done?
     
  8. Thank you thank you, all. I put it in the sink, winced* and covered it with a cloth. Oy!
    I read on a wiki answer that, "freezing causes the co2 out of solution, and there is no room for the co2 with the frozen water crystals," taking up space...or something like that. "The co2 will go back into solution as it melts."
    Wow. Weird to open the fridge up to.
    Thank goodness I saw it!! I was just loading up a few more cans because it was sooo hot today. Thanks all, near disaster (or mess, at least!) avoided.
     
  9. This must be the most exciting thread on PF
     
  10. Could be. Lol. Im just grateful anyone answered!!! Anyways, I'm no physics genius, so I figured Id throw it out there to the smart peeps.
    Besides, it's more fun than some calculus problem. (Maybe).
