A Monster in the Can
Spotting a strange item in your drink can trigger a lot of terrible emotions. For one, you stay off the drink totally, if it is something that shakes you terribly. Finding this junk in your can of Monster drink will definitely leave you less enthusiastic, to buy another can in a hurry.
The internet explained this growth in the can, to be a hardening of a sweetener used in the process of production. It could be xanthan gum or molasses, both of which are common sweeteners used in the production of sweet drinks. The person that discovered this will most likely stay away from Monster drinks for a while.
