We spent this weekend in Cape Cod w/ Frannie's family -- her family has been renting the same small cottage by the beach in Truro for 35 years or so, and we spend a lot of time out there in the summer. This year, our old friend Tati introduced perhaps the greatest beach innovation ever. Â The Waboba. Â For those who have yet to experience it, a Waboba is a ball that bounces on water. Â The ball is made of gel, and is wrapped in wetsuit-like material.It's amazing -- so fun in so many ways. Â We played in a small tidepool, close together. Â We played in the ocean, skipping the ball, long distance, up, over and across the waves. Â It seems silly to write a blog post about a beach ball, but this is really something special. Just check out a Youtube search for Waboba to see how people are using it (and how many people are filming it). Â We had the Waboba Extreme, which sets you back $8.99 . Â If you're spending time in the water this summer, I highly recommend doing it w/ a Waboba.
