dunno. i pesume that it would stay on the floor because there is helium every where. of course helium + helium = helium
yes , but wwhat about a ballon full of helium, in earths normal atnmosphere? it floats!!! so helim floats. i think we where talking about helium filled tyres? who wants to drive with helium filled tyres in a helium filled enviroment? mark k ----- Original Message ----- From: "Tom Richardson" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, June 24, 2002 11:39 AM Subject: Re: nitrogen filled tires > Mark, > > Imagine a room full of helium.
