Take some into deepest space (could take you several trillion light years) and you might find out.

Let us know how it goes.

(ie, v.cold)

WHAT? You'd need 50/50 iso to pure to stop freezing?

Jesus, that's gonna cost!

No way Hosé.

You're looking at 50litres of iso in a 500l wfp tank to avoid freezing at -4.  Hmmm.

Most of the time it's not that cold, you prolly just need 25litres of iso.

What's that to buy?

I'll eBay some.

Hang on.

ok, 5l is £10, so a 500l tanks needs about £25 a time.

Might pay.  Bit pricey though.

You'd be chucking in a hell of a lot of what is basically a nasty chemical into the grass and flower beds etc.

We use iso in our water, it dosnt stop it freezing but we generally get a felling it does help to a certain extent, we also feels it gives it a better a clean..
