General community for news/discussion in the UK.

Less serious posts should go in !casualuk@feddit.uk or !andfinally@feddit.uk
More serious politics should go in !uk_politics@feddit.uk.

Try not to spam the same link to multiple feddit.uk communities.
Pick the most appropriate, and put it there.

Posts should be related to UK-centric news, and should be either a link to a reputable source, or a text post on this community.

Opinion pieces are also allowed, provided they are not misleading/misrepresented/drivel, and have proper sources.

If you think "reputable news source" needs some definition, by all means start a meta thread.

Posts should be manually submitted, not by bot. Link titles should not be editorialised.

Disappointing comments will generally be left to fester in ratio, outright horrible comments will be removed.
Message the mods if you feel something really should be removed, or if a user seems to have a pattern of awful comments.

This study is such bullshit. They took 300 teabags and boiled them in 600ml of water while stirring at 750rpm for an unspecified amount of time, and claim their method to be an accurate simulation of making a cup of tea.

I had trouble believing you at first so I hunted down the study https://www.sciencedirect.com/science/article/pii/S0045653524026377?via%3Dihub to verify. You're completely right!

Three teabag types were purchased online (Amazon and AliExpress) or in a local supermarket. The online-purchased teabags were ordered empty (with no tea inside) and with a known polymer composition

The third teabag type (sample 3), bought in the supermarket, was a regular tea brand of green tea

300 teabags were transferred into a 1 L beaker (pre-washed and sterilized) containing 600 mL of Milli-Q water at 95 ◦C with constant stirring (750 rpm).

It sounds like they were using a magnetic stir bar rather than a spoon or rod but still, 300 teabags, most of which coming empty from Amazon or AliExpress in 600ml is ridiculous.

It’s almost too absurd to believe.

There’s a conversation to be had about microplastic contamination, but this study feels and sounds like bad faith argument.

They probably microwaved the water too, and didn’t use a saucer. No mention of when they put the milk in?
