carbonation, stat! (carbonation of my barley/corn ale)

I made the first beer in years that I liked, just sampled it the other day.  It was a small 1.5 gal batch of malted barley and malted corn (4:1), infusion, fuggles hops early addition and nottingham yeast.  I went nuts trying to keep clean and it paid off!  I sugar primed a small sample, let it bottle condition and it was great.  I then wanted to carbonate the rest in PET bottles with a carbonator cap and realized my tank was empty and no one fills them on Saturdays - bastards!

Here's my rapid carbonation method.  I popped 5 grams of dry ice into each liter of brew and capped it securely.  It dissolves in a few minutes.  I'll chill and it's ready.  I'll let you all do the calculations to confirm I placed the equivalent of 2.5 volumes of CO2 in each liter of beer.  And don't worry, no need to use the Redlich-Kwong equation of state (that's a joke).

Here's a pet bottle with the flat beer dispensed from my secondary and a block of dry ice from Graeter's.

I pounded the piece into little pieces and weighed out 5 grams.

Tossed the CO2 chips in, capped it and tossed the bottles in the fridge.

Then the extra dry ice was used for my amusement.  I tossed some in warm water and watched it.  I also tossed some chips in my mouth and pretended I was a rabid dog with all the smoke pouring out of my mouth.  The girls were away, so no one could see how hilarious I was.  

Warning:  I have put dry ice in my mouth a thousand times, it was one of the many ways we'd amuse ourselves in graduate school - I am a professional!  This can result in a great deal of harm if done incorrectly.
