Thanks @cowman

Unfortunately #borax is prohibited for sale in UK and EU. Depending which parts of the internet you read this is either because of birth defects in rats, or else it’s a shadowy #conspiracy by Big #Slime.

We have #BoraxSubstitute, sodium #sequicarbonate, (sesqui is one and a half). Experiment 3 was sodium bicarbonate, but what’s half a carbonate between pals?

[What will a # added to BoraxSubstitute do? 10000 years from now a Mastodon #archaeologist will find towels?]
