The Rehbinder effect, a phenomenon that makes cutting glass with a scissors underwater possible.

I’m getting more and more suspicious of water. What does it know that we don’t?

The Rehbinder effect is indeed a phenomenon that enables cutting glass with scissors underwater!! _What is the Rehbinder effect?_ 1. _Surface tension reduction_: The Rehbinder effect is a phenomenon where the surface tension of a liquid (in this case, water) is reduced when it comes into contact with certain materials (like glass). 2. _Adhesion and friction_: This reduction in surface tension allows for increased adhesion and friction between the glass and the scissors, making it possible to cut the glass underwater. _How does it work?_ 1. _Water's surface tension_: Normally, water's surface tension prevents scissors from getting a good grip on glass underwater. 2. _Rehbinder effect kicks in_: When the scissors come into contact with the glass, the Rehbinder effect reduces the water's surface tension, allowing the scissors to "grip" the glass. 3. _Cutting becomes possible_: With the increased adhesion and friction, the scissors can now cut the glass underwater. _Interesting applications_ 1. _Underwater cutting_: The Rehbinder effect has practical applications in underwater cutting and demolition. 2. _Materials science_: Researchers study the Rehbinder effect to develop new materials and coatings that can manipulate surface tension. 3. _Biomedical applications_: Understanding the Rehbinder effect can also inform the development of biomedical devices and procedures.

Me: mom can i buy this diamond-tipped glass cutter Mom: we have glass cutter at home Glass cutter at home: 🤷💀
