This is my first time hearing of Helium. Does it have any advantages over Nitrogen?

If someone barges in asking what you're doing, you'll get a good laugh out of them?

[globular-toast]

I'm really surprised that people think Nitrogen is laughing gas. I thought everyone knew 80% of Earth's atmosphere is Nitrogen.

I meant because your voice would be high pitched from the helium...

Availability? Helium at any party store, but I thought you needed to do something illegal or jump through hoops to get laughing gas

Laughing gas is nitrous oxide (N2O). I'm talking about normal atmospheric Nitrogen (N2). Nitrogen is available anywhere and significantly cheaper than Helium. Nitrogen can be used for welding or for brewing certain types of beer.
