Sandbag challenge

I wonder whether they could even out the results by getting the engineers to write some new sandbagging directions?

Researchers at the University of Manitoba conducted an experiment (PDF) in which they asked two groups—one made up of professional engineers, the other of volunteers given standard instructions—to construct a dike using standard sandbags. The professionals were able to create a sandbag dike 12 feet tall that proved quite effective. But the 6-foot-tall dike prepared by the unsupervised volunteers failed when the water reached its peak level.
