Quick Carb Beer Bottles

I'm wondering if anyone has come up with a DIY or found a tool to carb a regular 12/22 oz beer bottle with CO2. Im looking for a design to quick carb those beer bottles that didn't quit carb up enough or you just want to drink it without waiting two weeks for conditioning.

It's kind of tricky, but a SodaStream will kind of work for this... however I don't recommend it. You end up with a TON of foam all over the place. I use it sometimes to test a batch before I've carbed it to get an idea of what to look forward to. It won't carb a bottle, but you can use it to carb a small sample instantly, and then you get to wash the entire SodaStream, and wait about two or three hours for the foam to go down in the sample.
