Re: question about VDB

A magnetic stirrer has a motor that spins a magnet underneath a platform.
You drop a plastic-coated steel slug into the solution you want to mix, turn
on the motor and it spins the slug, stirring the solution. Works great!

My wife used to work in a R&D lab and she rescued a magnetic stirrer from
the dumpster, thinking I could use it for photography. Oh yes, I've got a
smart wife! It works great for stirring pigment into gum.
