I thought the game seemed like fun, with the option of customizing the activities. I can see using it with kids to teach some real life lessons. How about an educational version? Maybe make them a little more conscious of ethics, advertising etc. Or, of course, a business setting ice-breaker, or a way to learn about your fellow players.
I really liked the water filter idea. We have a whole house system for our very hard water, but it really doesn't do anything for contaminants.
I also liked the bottle thing, and would actually use it. A lot of bottle are designed to be stored upside down, but a lot are not. Propping the old one on top of the old, even with tape, is a pain.
I felt sorry for the soda guy, even if he is a lawyer. Isn't that a pretty hard space to break into, it seems like there are millions of beverages out there. I have to admit I really don't drink cold flavored drinks - I drink water, or coffee or tea. But a lot of people are more interesting than I am.
Agree that Rohan is a more than decent guest shark, he is an actual investor not on the show to hawk his own company.
