Re: [Phys-l] Oobleck



Yea, there are great YouTube videos illustrating this. Even on a small
scale, you have the keep the oobleck covered so it doesn't dry out. I
think the ones on YT of people walking across pools of this stuff are so
large that evaporation is not much of an issue.

Our Physics Club is excited to take on the challenge of setting up a
large-ish scale demonstration of a non-newtonian fluid for an annual
spring bacchanalian affair that is a tradition at Le Moyne.

I have some limited experience with smaller-scale demonstrations with
your basic corn-starch & water oobleck. I have found it to be a
giant PITA to mix and KEEP mixed. The Club is interested in any and
all advice and wisdom from anyone who has put on a larger scale demo –
best proportions, advice on how best to mix the stuff and KEEP it
mixed for a stretch of at least a few hours, and so forth.

Anyone done this?

Thanks,
David Craig
