Your heads up prompted me to dig my PINGI outta my boot.
It's been sitting there for months.
Well I weighed it and assuming it's reached max saturation by now it came in at 376gm
After 6min at 500w in the microwave and leaving to "let off steam" it weighed in at 330gm
So it's only really capable of holding about 45ml of water which looked a little bit lame!
Alas, like the Tesco advert goes
EVERY LITTLE HELPS
