If you can explain to him what was special.about flavored water with no proven health benefits then I'll believe it was the product. To generate sales in a very crowded food and beverage space, and do it twice to prove it wasn't a fluke was the hard part. High profit low cost product. The sports apparel space is similar in that regard so I wouldn't bet against NoBull either.I sent the link to my 21 year old who wants to be an entrepreneur.
