Yesterday, at Discovery Days as part of the Bay Area Science Festival - I had my own chance to run across a pool of oobleck!
UPDATE: In January 2014, Hong Leong Bank puts my accomplishment to shame with their 8,000 liters (over 2100 gallons) of non-newtonian fluid in Kuala Lumpur, Malaysia! You can watch people running, jumping and even BIKING on it!
And, remember, this is an advertisement for A BANK?!
