I keep 'trying out' Mastodon, I actually really like it, however, I've been using various platforms for years and I've never really put myself out there, well, once, when some art I published hit a nerve with some people and had hundreds of likes and follows overnight, had to turn my phone off at one point, it eventually all kind of freaked me out. Anyway, here I am. Hello.

I started a new jar, in parallel with the old jar. The only difference is that the new one uses distilled water instead of tap water, and about half as much yeast extract. I inoculated the new jar with about 8oz from the old one.

Random Stuff that came up as I was talking to the kids. This one based on their Q - what's the most viscous liquid

Pitch is 2 * 10^10 (20 billion) times more viscous that water

See the longest running (since 1929) - Pitch Drop. 9 drops so far (none have been observed actually dropping!) - 10th eagerly awaited.

Today my new power supply arrived! So I've lowered the voltage to 70 mV, which I gather is roughly equivalent to the membrane potential of a typical cell. This forced me to switch to DC instead of AC because my h-bridge min voltage is 4.3V.

I've decided to go for a positive control and do my best to actually grow some bacteria! I added Christmas tree water to seed the jar, plus some yeast extract to feed them. If it fails I'll add sugar
