Here's my take on the subject:

There is no harm in giving a team the opportunity to experiment with liquid substances. There are a million and one engineering careers out there, and a lot of them deal with water because the underwater ecological system as well as the change in planetary structure (e.g., things that cause ocean earthquakes) are important issues.

I personally think Dave was introducing his team to the concept as a matter of introducing and inspiring them to take interest in a possible career.

However, I agree with Cory. There are an incredible amount of safety risks, as well as an incredible amount of competition setup logistics. What happens if something goes wrong? Flood the stadium?
