I have a stash of grading pens we use in my classroom. The ends have started to be cut off. Yesterday I told my students to not use the scissors to cut the pens because it would dull the scissors. Then one of my students said she is the one who’s been doing it, but she didn’t use scissors – she used her mask.
Then she showed me – she sawed her mask ear strap back and forth across the pen. It got hot, then slid right through the pen and cut off the end. Mind blown!
Maybe a mask could be an emergency supply… could you rub it on a piece of wood and start a fire? This needs more investigation…
