Mission statement: On this blog we explore why homeschooling can be a better option for children and families than a traditional classroom setting. We'll also explore homeschooling issues in general, educational thoughts, family issues, and some other random stuff.
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.
