Of washing machines and crisps

I note with interest that there is a hand wash setting on my washing machine. How can this be?

This is a right wonderworm.* I may have to write to Hotpoint.

It’ll be like the time I wrote to Walker’s asking them how they put the flavour on crisps. This, by the way, is a good way to get vouchers for free crisps. Not a good way, however, to find out how they put the flavour on crisps. I don’t think they knew. Maybe it’s magic. Wheeeeee.

* Like an earworm but, you know, different.
