Mixing nitrogen with air

From the AA:

"Slower rate of pressure loss – nitrogen molecules are larger than oxygen molecules (which make up 21% of compressed air)"

Crap you're right. I assumed that because nitrogen has a higher atomic number its molecules would be bigger. They are in fact slightly under 3% smaller.

I still think its a con though :-P
 
DONT DO IT!

Nitrogen reacts violently with air - you'll cause an explosion! Your tires will explode and send rubber everywhere.
 
Damn you B.O.F.H.! I just quit smoking out of fear of stepping into a high nitrogen bubble in the atmosphere!

Ahhh but clearly, you forget that at the concentrations in the atmosphere the Nitrogen is inert.. its only when its gets mixed with a SMALL amount of air.. then you're screwed.
