The Mercury is in a glass tube with two wires and the tube is attached to the bimetallic strip in such a way that the motion of the Mercury due to gravity as the strip moves will close the circuit between the two wires. The Mercury is just being used a liquid conductor.

Well, I wish it would. It just stays on the non-working 5G unless I change the preference setting.

Thanks, I'll reach out to Google Fi support to see if they can help.

I do, but we have had several extended power outages this year and I often have to rely on cellular data in those times.

You would think the phone would do it on its own, but it doesn't seem to. The default selection for preferred network type is 5G. The only other options are LTE and 3G. There is no way to leave that setting blank or automatic.

The Wi-Fi calling does generally work, but we've been experiencing a lot of power outages lately and I have to rely on cellular data.

Hmmm maybe. Google Fi and Mint both use T-Mobile towers.

Not sure what counts as 'regular' circulation. But there's a Canadian 'toonie' in circulation that has a glow in the dark Aurora on it. https://www.google.com/amp/s/www.cnbc.com/amp/2017/06/27/canada-released-glow-in-the-dark-coin-150-year-anniversary.html

Some Roku remotes support this. You issue the command from the mobile app

If you need collaboration you can self-host collabora for free. https://www.collaboraoffice.com/code/ It uses libreoffice code. It's also a supported backend for collaboration in nextcloud.

Unfortunately there is no way to leave that setting blank or set to automatic that I can see or find.

Again, there is no 'automatic' option. My only options are 5G, LTE, and 3G. It's also not possible to leave the setting unconfigured. The default is 5G.

I have my modem and WiFi on a 1500va backup, but we have had several extended outages recently.

Yeah, that's what I've been doing. It's annoying though because I have good 5G coverage in other parts of the city and I don't want to have to remember to switch back and forth manually 🤷🏼‍♂️
