Bzzzzzrrrrrrt.  :-)  Wrong, Jeff.  The average molecular weight of air is
approximately 29 g/mol.  (N2 = 28, O2 = 32, 20% O2 and 80% N2 --> ~ 29
average.)  The molecular weight of propane (C3H8) is 44 g/mol.  Under the
same conditions of pressure and temperature, propane is 44/29 or
approximately 1.5 times as dense as air.  However, your recommendation is
still valid.  But, beware!  The propane will tend to settle at the lowest
point and can continue to be a fire/explosion hazard for quite a while
unless  you are outdoors and have a decent (or at least some) breeze.
