Am I going crazy? One toothbrush for every person. I’m a monogamuggle, and I don’t even share a toothbrush regularly with my wife. If you insist on the counter being tidy, put them in a drawer. Also prevents aerosolized fecal matter from getting on the toothbrush head.





It turns out, that for the values we are talking about here, it actually more or less does! A lemon has a pH of around 2.5, while “Flow” has an advertised pH of 8.1. This means roughly that to neutralize 1L of this water you need approximately 0.4mL of lemon juice or about 8 drops/half a gram. It’s hard to tell how much a “spritz” is intended to be, but a single lemon contains about 60mL of juice, so this represents about 0.67% of the total juice inside.
It’s a surprising consequence of using a logarithmic scale for pH.
