i was at my computer, browsing through the new posts and i opened a bottle of "Henry Weinhard's Root Beer." i took a small drink, then put it back on the coaster with the cap off. i finished reading a post and grabbed for my root beer, but white foam was comming out of the top very slowly.

 

the white foam isn't like normal root beer foam.

it was sticky, like a marshmellow (but foamier).

it tasted kinda like an acidic marshmellow.

and it wasn't pouring over the sides (well, slowly).

 

does anyone have any idea what this could be?

 

just incase it helps:

i was eating an orange marmalade jelly and peanut butter sandwich just prior to taking the first drink.

i am alone, so it wasn't a prank (and my parents didn't do it).

this hasn't happened with any of the 5 root beers, that came in the same package, that a drank this week.

and i am now going to throw the drink away because i don't trust it.

 

<edit> now that it's died down a bit, it looks like soap bubbles. i took a sip of the root beer underneath and it tastes normal, kinda flat, but it was only a sip. Now i will throw it away...

 

<edit>... maybe one more sip... yup, definitely flat.

Did you have a look at the contents of the root beer?

ingredients:

carbonated water,

high fructose corn syrup,

carmel color,

vanilla extract,

natural and artificial flavors,

phosphoric acid,

sodium benzate (preserves freshness),

honey essence,

acacia sassafras extreact.

it has nothing to do with chemistry, this is a clear sign of witchcraft. Burn all your neighbors houses, since the government no longer participates in aid of holy purgings (not publicly at least)
