Today I was having a chat with
one of my Chemistry professors.
We were talking about the compound,
and how it could kill a person if
they didn' t breath in any oxygen.
He told me the same was true for helium
and told me about this news article
he read about some guys who died
while in a giant helium balloon due
to lack of oxygen.
Then he said,
This is kind of morbidly amusing, but
imagine these guys in this balloon
and as they yelled for help,
the pitch of their yells got
higher and higher
as they neared death."
