Why do deoderant cans still have fluid in them when they run out?

Question:

every time i run out of deoderant i shake the can and i can here the fluid moving.

Answers:
The same reason that you can't ever use the last half inch of stick deodorant without it falling out/breaking apart. The cap on the top creates enough suction to yank the remainder right out of the dispenser. It's one of lifes major little frustrations.

(But if you call the company to complain they'll send you lots of nice coupons!)

You didnt run out of deoderant you ran out of pressure to push the deoderant out of the can.
