I've met more than enough people, adults included, who believe for whatever reasons that the Rocky Mountains can be seen from Vancouver. Why? Haven't they looked at a map? How on Earth could someone possibly see them from Vancouver? Vancouver is in the very south-western corner of the entire country of Canada. The Rockies are on the border between B.C. and Alberta.

one of the Universal Laws of Gravitation ::
the gravitational force on an object increases as mass increases

helium has mass
how come when you add more and more of it, it flaots higher? shouldn't it get lower ( you know what i mean)... i never really realized this but i has a science test today and was like wait a second!!!
-edit-
I know helium is lighter than air, does that have anything to do with it? it still has mass though? help please..
