Week 5 Homework: Post thoughts on this evening's discussion

I like skim milk.

I drink it as substitute for liquid milk because it's cheaper, durable and it does not take that much space to store.

I didn't know skim milk are considered to be waste in the past.

Farmers in US played around with skim milk, and the story was quite interesting.

Particularly I liked the story milk dealers tried to do marketing for skim milk for acquiring new consumers.

"She can be yours"

Hmm....that sounds pretty good!

Helium gas can be used to make balloon float on the air.

Helium gas can make your voice pitch higher.

Helium gas can make balloon to float because helium is lighter than oxygen and nitrogen in atomic weight. That's why balloon contains helium gas can float on the air.

If helium gas enters in your lungs, the voice coming out from throat can be transmitted faster than when is normal air. Then number of times the voice sympathize while passing throat increases, causing wavelength shorter.

That's why when the voice comes outside world, its pitch is higher.
