upside down

i have two ballpoint pens sitting in a drawer, nib-end down, above my heater.
my hope was that soon the ink would return to the nib end so i can use them.

but nothin' doin'.

i don't want to be a cheapskate, but neither do i want to be a western consumerist who chucks stuff out just 'coz it's a bit broke.

any ideas anyone? how do i make the ink go where it should be?
