Less dense things will float in more dense things; like cork floating in water or helium floating in air.
In the video above an aluminium foil boat floats on sulphur hexafluoride (SF6), a very dense gas.

I realize it’s not your fault (and a lot of websites have the same issue) but it seems like the vast majority of your youtube links are broke due to the videos being pulled. You get me all excited from the title/blurb and then…….nothing *sigh*
I do like seeing a small chunk of dry ice in a bowl and then floating a balloon on it. Same effect but the boat’s probably more impressive (but probably harder to float due to amount of displacement than a balloon, which almost floats in plain air as it is.)
