> some kind of magnetic board Sounds like a giant Etch-a-sketch? There are these small electric blackboards that you can push a button to reset: https://myboogieboard.com/pages/blackboard-smart I wonder if they make a giant wall mountable version?

Slightly off topic, but if you ever write on a whiteboard with a sharpie, you can write over the text with an erasable marker and then wipe it away.

You can do the same with a Sharpie. All inks contain a solvent for their pigment, so you can use the same marker to remove the same ink. Just mark over it and immediately wipe it off.

I bought this 4'x3' Black Glass Board back in 2017 for $150! I write with white and neon colored liquid chalk markers and it's the best! Here: https://a.co/d/hlrwPHQ Enjoy it.

Wow! Do you then use white board erasers, chalk board erasers, paper towels, microfiber clothes, squeegees ;P, or what do you use then to erase?

Ditto, same size, same thing (different brand), cheaper pickup ~ $70 (2024) "Magnetic Glass Board", chose black since it seemed less NPC.

Lots of cool pens on Temu - https://www.temu.com/search_result.html?search_key=Liquid%20...

Also cool. Looks great under a UV light too.

If you want to remove Sharpie, use IPA...isopropyl alcohol...India pale ale remains useless.

Isopropyl removes all inks and glues. It's incredible.

It's also fantastic to wash your hands with when doing cell and tissue cultures and trying to avoid contamination.

I recommend chalk. Its a little dusty but works great. Seems to be nontoxic and low in the chemicals and plastic department. Chalk. Even comes in colors. I'm not joking.

Also it's actually gypsum. Same material plaster and plasterboard is made from.
