Right Slubbers - go to your Plastic Cupboard Of Carnage, right now, this moment.
Rummage, dig and delve to find a box, with appropriate lid (I know, it's difficult, but I promise you it will be worth it).
Tip your 3/4 bag of pearl barley into box and seal tightly.
Now, go and find your phone or iPod (other mp3 players are available).
Got it?
Is it switched on?
Yes? Ok then, now drop it down the loo. (flushed or not, it won't make much any difference to the final outcome)
Quickly retrieve the gadget.
Right - now this is the important bit - do NOT switch the phone on.
If you can open the battery compartment, it's best to do so.
Seal the phone in the pearl barley grave box and put the box in a warmish place, but not the oven, like an airing cupboard.
Now, leave the gadget sealed in the box for 3 weeks until completely dry. The pearl barley will have absorbed all the moisture from the dunking and the gadget will smell of poo be as good as new.
I await your thanks.
