Last year at the family picnic, you got slaughtered by Aunt Suzie in the swim race. That will never happen again. For one thing, you've cut the brake cables on her Chrysler. For another, you'll be wearing Extra Force Fins, designed to give you better thrust by channeling the water. Add the "whiskers" and you can literally shift gears underwater: Snap them a few clicks inward and the water speeds up as it's forced through the smaller, center channel; snap them outward and you float more than fly.

Excellerating Force Fin
"We outswam dozens... in these speedy fins. They're perfect for underwater hockey or just hanging 'round town.
Bonus: The green wings flare out for added control"
