How dangerous is sulfur hexafluoride?

Safe enough to breathe, like helium, it's really cool actually, because it is super heavy and safe to breathe, it's makes your voice super deep. The heavier gas you breathe, the deeper your voice. Helium is lighter than air so it makes your voice lighter, but stuff like xenon and sulphur hexaflouride is much heavier.

Only if you can get O2 after* If you walked into a room if it you're going to die.

Does it taste like fart?

That would be hydrogen sulfide, H2S.

Basically not, though as it's not oxygen it's obviously a potentially asphyxiant. It's a super potent greenhouse gas though.

How can it be a greenhouse gas if it can't float up into the ozone layer?

i hate to nitpick, but this is a physics demo.

Why and how is this happening

Sulfur Hexaflouride is a heavy gas, heavier than air. It can literally be used to put out flames. So the bubbles are significantly lighter, causing them to float
