I also thought about something not in the book:  why does a helium balloon
rise?  Don't tell l me it's lighter.  My cat is lighter than I am and he is
not flying around.  The gas inside the balloon must be exerting pressure in
every direction, so the force cannot be from there.  Where is the force
here??


Do you not know this or are you cleverly feigning to test the list for
science blindness?
