There are great videos on YouTube. All of the large scale versions that I
have seen used cement mixers to mix the corn starch and water. They have
also done it on the Discovery Channel program, Time Warp. Maybe they have a
blog that explains it.

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.
