Everything you just wrote has made me understand that I should write on a balloon with a Sharpie.

This sounds fun. Thanks.

Except the balloon is a metaphor and the ink is hubris.

Cover that bad boy top to bottom for a real octopus-reaction-like experience!

It should be noted, there are a variety of chemicals that will dissolve and carry away the ink from most things if you look for it. Of note, rubbing alcohol and paper towels work well.

Likewise, the paint markers which I make use of are easily removed by rubbing alcohol.

There's a useful trick many educators know: if someone uses sharpie on your whiteboard, draw over it with another whiteboard marker and you can wipe it up like normal. Also applies to glass and some other surfaces. Essentially the same process you're mentioning but different chemicals. But always be careful with solvents. If water or isopropyl alcohol (IPA) doesn't work, you should know what you're doing/using.

I lost a couch to this.
