Sulphur Hexaflouride is much denser than air.
Dense gases are weird in that they make sense but are still kind of unsettling.
True story: I once inhaled some argon because I was standing over the argon tank for a long time and I am a fool and I was like, “My lungs feel…smaller?” and then I had to go find a friend help me stand on my head. It clearly wasn’t a lot of argon because I didn’t notice a voice change and I didn’t pass out but I could *feel* it inside me and it was weird as all get out.
Did I just turn 24?
*Check facebook* Yup.
