Kathy,
After our event we brought the waste oobleck back to the science center in 5
gallon buckets and left them on the loading dock to deal with disposal the
next day. After settling overnight, each bucket had about 2 inches of water
on the top, the rest of the bucket was filled with a nearly rock hard mass.
We could not really remove it from the buckets. If we did this again, I
would obviously dump it right away.
