Fun with Chemister

This is cool:

The best part is the last fifteen seconds.

I wonder how hard it would be to get a tank of Sulphur Hexafluoride. Does anyone know?

After spending more than 15 years as secondary and tertiary science education and another ten teaching it, I was stumped as to why I had never seen either of these demonstrations. We have all seen how Helium makes your voice pitch higher, but who has seen someone inhale a *more* dense gas than air?

And who has seen such a perfect demonstration of different gas densiies than making something seemingly float on air, (when in reality air is floating on it!)

Great work.

Thanks. I'm glad you enjoyed the video.

I thought the floating in air part was the best.
