- I have often heard this one during beer parties... I never have believed this o
- one and have in fact tried the following experient:
-
- drop two cans of beer. tap one and not the other. Open at the same time.
- compare fizz. they are the same.
-
- But I think I have a historical explaination. This tradition of tapping a
- beer can actually comes from our german ancesters, transplanted to USA.
- When aluminum cans and glass bottles came about, they where used to
- "tapping" their kegs to relieve the keg of it's pressure by withdrawing some
- beer.
-
- Well, over the years, this has been transformed to liturally tapping on
- a can of beer...

- just my guess };)
