At time like this I hate notbeing a native speaker of English.
I'm looking for the name of these plastic whistle-things with a paper part that extends and unfurls when you blown inside that are usually present at birthday or new year parties.
(Answered! Thanks a lot!)

I have a story set in London in 1977, and I have questions about two scenarios.
#1:
Three guys see their best friends being arrested. They hurry toward their friends. The police (who are actually NOT police, but everyone thinks they are) think that the guys are going to attack, so they strike them down. The guys fight back. There is a fight, the guys are eventually subdued and brought to the police station.
What would they be charged with?
#2:
White workers at a textile mill hear that their fellow workers who are Jamaican and West Indian are mistreated, discriminated against, and underpaid by the bosses. The workers against this sort of behavior organize a walkout. One night they all walk out of the factory and stand outside saying various anti-oppression things in chorus, and making anti-discrimination speeches through megaphones. All told, there are about two or hundred of them (realistic number?) milling around outside the mill. Then, a racist party shows up and starts yelling things back at them through megaphones and chanting their own RACIST chants. In this scenario, what would the bosses of the mill do? What would the police do?
Thanks!
I need a female jazz/blue singer that a real enthusiast would listen too. I know nothing about jazz so I don’t really know what’s hot and what’s not.
Also, what type of duties would a bartender really hate doing?
