OK, I just saw the coolest thing I have seen in a LONG TIME! I’m watching Jay Leno and he has a guest on tonight, Mad Scientist David Willey. He is explaining sulfahexafluoride gas. Apparently it is a gas that is denser than air so he has a balloon filled with air and with sulfahexafluoride, and the sxf (I am going to call it that for short) balloon falls super fast to the floor, but that is nothing.
He opens up a large glass box (picture a fish aquarium) filled with sxf and they make tin-foil boats and they “float” them there in mid-air inside the box. Of course the bowls are floating on top of the denser than air sxf. They then blow bubbles at it and of course they bounce right of this mid-air.
Willey then shows how this gas will not conduct electricity by placing a 400,000 volt zapper inside the glass box and it immediately shuts off.
But, the BEST part was that the scientist called sxf the “anti-helium” gas. So Jay, says something like “you mean if I suck this in it will make my voice lower?” – he was joking, but the scientist wasn’t, he had Jay go right ahead. And wouldn’t you know it, Jay started talking and it sounded like a slowed down recording. He was cracking up and so was I. Willey then joined in as Jay called his other guest, Josh Duhamel, to come and try it, which he did – it was hilarious! Maybe the youtube video will come out soon.
