Not really any good way but you can look to see if there is a layer of yeast on the bottom.

There should be a slight bubbling on the cap, it being pushed out.

some people fill one 12oz pet soda bottle so they can tell by touch.

If you take a bottle and hold it up to the light so you can see through it, then tip it fully upside down and back upright, you will see several large air bubbles floating through the beer. A carbonated beer will also have very fine bubbles form and float to the surface.

This is not an indication that carbonation is complete or levels or anything like that. But it is a fine check to see if you are making progress.

Open one and if there is a phffft it is carbing.

Should only take 1 week to tell if it is in a 70 degree room.

Plus - you get to drink one then

I really like this idea, can you just use the same screw cap and everything? seems like a decent way of getting a ballpark estimate.

also, do the 22's take longer to carb than the 12's?

1. Pretty sure, never tried it.

2. Varying opinions on this, I'm of the camp that 12oz of a mid range OG ale finishes about a week before a 22 oz.

?? I don't think thats true. I've bottle conditioned a lot of beer. I can't specifically remember the pressure ever bubbling the cap out. I don't think it even happened on a batch I over carbed and the bottles exploded.

Please correct me if I'm wrong. I have 2 cases of bottle conditioned beer at home if this needs to be proven. I'd hate for a new brewer to see this and think his bottles weren't carbing up though.
