Question

I had some people over and they thought it would of been funny to open some of my bottles of budweiser and spit in them and close them is there a way to figure out if they were opend then closed

Answer 1

Jesus...get classier friends.  And for godsake go buy yourself more stinking beer...

Sheesh....

Answer 2

It doesnt pop when u open it

Answer 3

The beer will be flat. Try to pour it into a glass quickly. If it doesn't foam, it's flat. And don't invite those people over again!

Answer 4

Here's the fail safe way to find out if there's spit in your beer.

Pour it in the sink:

1 - If it goes down the drain, it's fine

2 - If it stays in the sink, it's got spit in it (the spit thickens the beer and causes it stick to the sides of the sink instead of going down the drain)

Either way, you'll be better off. IT'S ONLY BUDWEISER. Sheesh
