I read an article in the paper about how to use everyday objects to fix things.
It used my aforementioned cure for drying out cell phones in a bag of rice, using the sticky end of a Post-it for cleaning between the keys of a keyboard and using cookie sheets to help the reception of a router.
My router is an eBay purchase, so probably not the most efficient and it takes a while for the laptop to find the signal. I put an old cake pan under it, and I'll be damned if it didn't pick up the signal right away.
Must be the same technology as putting aluminum foil on the end of rabbit ears.
