Shunning and hissing, yes. Violent assault, no. This is one of the reasons I'm not a fan of the major pro sports, and fight the taxpayer subsidies and financing of their half billion dollar sports palaces.
You've never shot a Mentos fountain into a ceiling before? The warm foam mass has to accumulate somewhere, and as it slightly cools it loses the adhesive properties the carbon dioxide affords as it bubbles out, it becomes liquid again and becomes heavier, thus falling. Happens all the time if the ceiling is close. Landlords hate these things.
