So since we're aware of how to make artificial weather, does this mean we can actually control the weather?

Not all the SF6 breathed in will be exhaled. Due to its high density some of the SF6 will remain in the bottom of the lungs. Hang upside down for a few minutes whilst breathing and the small amount of SF6 that settled in the bottom of the lungs should be expelled. Although SF6 is essentially inert and has a low "known" toxicity in humans that doesnt mean that breathing the gas is a healthy thing to do (especially a lot of GAS)

the science guy on kimmel does cool stuff too. but it takes a certain type of host to make the entire experience great and fallon just nails it. kimmel is too much of an ahole and ruins the entire segment.

Watch with caution. Sulfurhexaflouride might not be toxic, but it can suffocate you if you're not careful. Since its heavier than air, the only way to get it out of your lungs is to hang upside down and breath for a few minutes. If you don't do this, it sits there and reduces the amount space for breathable air until you either get it out accidentally, or hyperventilate, pass out, and soffocate.
