Yes, that's what I said...

You could also put the plane in a very big oven and heat it up, thus
expanding the holes the rivets go it.  When the plane cools down, the parts
are riveted.

...except some people believe the holes would get smaller...

!

Still, I've never heard of that method.  Dipping rivets in nitrogen?
Really?  And I thought explosive rivets were cool.
