Yesterday, there were petri dishes everywhere. Miranda is doing a science experiment as part of her IB classes. Her experiment is evaluating the effectiveness of washing one’s hands with different agents: soap, antibacterial gel, etc. She prepared agar in the petri dishes, then cleaned her hands with each method and then dabbled her fingers in the agar. Now she’s waiting for bacteria to grow. It was a little hard for her to find hand sanitizer gel with 80% alcohol, but she and Tammy found some eventually. Not as bad as at the beginning of the pandemic when it was as rare as hens’ teeth.
And I got around to replacing the bathroom fan in the ensuite. When I did the one in the kids’ bathroom, I kept bouncing off things I didn’t know or wasn’t certain how to do. It made it considerably more difficult. But today, knowing what I had to do last time, it was only a couple of hours, if that.
Old fan ready to be removed 
New fan installed and working
The old one wasn’t making huge amounts of noise like the kids’ one was before I replaced it, but it never seemed to be very effective at moving air. Hopefully this one will work better.

I made this post on the new Mac Mini, and dang it’s fast. I don’t tend to use the main computer when I’ve got my work MacBook upstairs, but I might have to change that.
New fan looks good.
