# Waterslide for Ducks

June 20, 2017

Everyone loves a great waterslide: it’s fun to swoosh down and make a giant splash at the bottom. But why should we humans have all the fun? Ducks love water — and it turns out they love water slides, too. At the South Carolina State Fair, someone set up a waterslide and let 6 baby ducks play on it. Ducks are great swimmers, thanks to waterproof feathers, lots of body fat that helps them float, and webbed feet that paddle fast. But as we see in this video, they’re happy with 1-inch-deep water, too. It looks like there are snacks at the top of the ramp as a bonus treat. If only we humans could have one of these in our living room…

Wee ones: Who has more feet, you or a duck?

Little kids: There are 6 ducklings waddling around on the waterslide. If one’s on the slide and one’s waddling up the ramp, how many are left snacking ?  Bonus: How many of those webbed feet do the 6 ducklings have altogether? Count up by 2s if you want!

Big kids: If each of the 6 ducklings takes 4 turns, how many duck-slidings happen in total?  Bonus: The video lasts about 30 seconds, and the 6 ducklings each slide once. If they took their turns evenly spaced, with one starting right at 0 seconds and the last one at 30 seconds, how many seconds apart did they start their turns?

The sky’s the limit: If these 6 ducklings are named Quinn, Quan, Quickie, Quackie, Queenie and Quipper, how many ways can they line up so that Quinn always slides first?
