Here's some nerd candy.
The corn starch mixture becomes more viscous as pressure increases, so forced oscillations form these patterns

Surface tension is awesome. There would be no surfing without surface tension.

Can you put that sentiment into graph form...
Or a scientific formula?

Thanks for asking. Here's some light reading that should support that statement.

Yeah, maybe a nice histogram with the spreadsheet.

How 'bout a new post on the physics of noseriding?
From the science guys...
I've seen some good explanations before...
But it's been awhile.

I've only gotten a cheater five up there, so I don't know if I'm qualified to make a hypothesis. I've thought about it for hours though.

The basic aspects being...
Forward motion...
Speed...
Downward pressure of rider's weight...
Downward pressure of water on tail of board...
Other aspects...
Surface tension...
Water flow...
Tail/fin configuration...
Ow.

steepness of wave, and size of gut.
(this is now surf related)

Well you can highline... Lowline or midline... I was never that good at math... Just surfed too much I guess...
