We’ve had an email from Ellie:

I’ve found about half a dozen opened bottles of soda water and tonic water in the back of our drinks cupboard from last Christmas (I don’t know why there is so many!) They’re flat now but I know you can use soda water for stain removal so I wondered if you knew of any ways I can use them up.

Soda water (aka Club Soda) is a useful stain remover for liquid spills but I’ve heard that part of it is how the fizz “lifts” the stain – so I’m not sure it’ll be still as useful for that.

Some sources recommend soda water as a mineral-rich water for plants – flat stuff would still work for that – or, similarly, tonic water can help keep cut flowers fresh (used one part tonic to two parts tap water).

One other thing about tonic water – the quinine in it causes it to glow in the dark. We’ve obviously missed Halloween now but it lend itself to some fun decoration ideas…

Any other ideas for how to use up those fizz-less drinks?
