Hello, guys, I am new here. I'm wondering, what kind of sand should I use to reproduce this phenomenon: http://www.youtube.com/watch?v=X7LpmE9hl-c&feature=related
I've tried several kinds of sand, but the phenomenon hasn't observed.
What density should sand has? What is the fraction (diametr) of sand?
Thank you.
PS: I don't asking about origins of this effect. Just want to reproduce it.
