NASA was considering sending canaries into space to study them under zero gravity. The project was scrapped when someone realized that in spite of having sufficient water supplies, they could die of dehydration within a few hours. Why?

Because birds need gravity to swallow. Otherwise they would'nt be able to consume anything.

Birds, unlike humans, need gravity to swallow. Humans can swallow even while hanging upside down.

Came up with a few the other day, trying to space them out. Another 'what am I' riddle, this one should give you a definite "aha!" moment when you figure it out.
Push me, pull me
One end is quite prickly
I sound quite aggressive
If I'm said too quickly
What am I?

A man phoned his daughter to ask her to buy a few things he needed for a trip. He told her she would find enough dollar bills for the purchases in an envelope on his desk. She found the envelope with 98 written on it.

In a store she bought $90 worth of things, but when it was time to pay she not only didn’t have $8 left over but she was short.

By how much was she short of cash, and why?
