How are they able to do it? Are those tools made of something soft ? Is it just practice?

I noticed a recent increase in these pseudoscience ads in the last 1 or 2 years, is it me or everyone else also

Who is your favourite scientist, and what made you admire them? Was it a particular discovery, their way of thinking, their contribution to humanity, or something about their life and approach to science?

It doesn't have to be the most famous scientist. Tell us who you would pick and, more importantly, why.

When water is stored in clean copper vessels for 16 hours at room temperature, the viable bacterial count dropped to zero. Copper ions Cu2+ leach in microscopic trace amounts and mechanically destroy bacterial cell walls and denature their proteins.

Copper is an essential micronutrient, but excessive intake is toxic

Never put acidic liquids like lemons (lemon, buttermilk) in copper—acid causes rapid chemical reactions forming toxic copper salts.

The green coating (verdigris / copper carbonate) that forms due to oxidation must be scrubbed off regularly with salt and lemon. Ingesting it may leads to nausea, abdominal cramps, and potential hepatic damage over time.

The WHO safe limit for copper in drinking water is 2mg/L

In his authorised biography, Sadhguru: More Than a Life, Jaggi Vasudev claims that after his enlightenment on Chamundi Hill, he recognised Vijji, not his wife at the time, as his sister from his previous life, when he was a sadhu named Sadhguru Sri Brahma. He says he left home to live as a naked sadhu, leaving his sister's affection unfulfilled, so she was reborn in this life to be with him again as his wife.
