The idiots from Xtinction Rebellion annoyed Wellingtonians in order to have their voices heard.

Why would anybody bother to unglue them from the windows? Just leave them there. Once they feel the call of nature, the TV visuals would be much more interesting.

But it was the orange flare smoke blowing in the faces of the marchers that tweaked my interest.

Was the idiot arrested for this criminal offence?

What are flares made from?

Flares produce their light through the combustion of a pyrotechnic composition. The ingredients are varied, but often based on strontium nitrate, potassium nitrate, or potassium perchlorate and mixed with a fuel such as charcoal, sulfur, sawdust, aluminium, magnesium, or a suitable polymeric resin.

Well, that sounds like a delightful combination to release in a city street, blowing into the faces of your supporters and innocent passers-by.

What does the material safety data sheet say about orange signal flares?

Yup, these infantile idiots certainly love other people and our planet.
