Steve Spangler's heavy air lowers Gary's voice

Maybe this would've helped Gary become the voice of the DIA train?

Our science guy Steve Spangler was on the 9NEWS morning show on Monday, talking about the science of heavy air.

So he had us breath a gas, which lowered our voice.

It was pretty funny, and got me thinking... maybe this is what I needed to beat Alan Roach to be the voice of the DIA train!

Eat your heart out, Roach...
