Another picture of the man and woman. The middle aged man has scientific writing near his picture. The young woman has a cute 70’s look.

Forever and ever I thought that if the tube did not spin, the signals would be crap. But our spinner was down for weeks and everything was just fine. Signals looked just like they always looked. What do I not understand? (Spinner is back to working now, actually.) πŸ§ͺ #chemsky

Newly cleaned hood bench surface.

I was in grad skool 89 years ago but I have this memory that we used to buff our bench tops with mineral oil to make them shiny/pretty? Did I? Did anyone else? Do you do this or something similar now? πŸ§ͺ #chemsky

Max Jr can probably tear a mouse or bird to pieces yet I feel the need to mash up his pΓ’tΓ© up for him.

Small pet peeve, found on some glassware. I know the markings are only β€œ5%” accurate anyway but why not just go all the way? What, are they saving some money doing this? #chemsky πŸ§ͺ
