Home #Makerspace: DIY Drain Pipe Regatta (or Rain Gutter Regatta)

On a hot summer day, nothing beats a cool, breezy scientific adventure.  The Drain Pipe Regatta is a great investment for a classroom or backyard exploring space, as it helps teach the basics of fluid dynamics, buoyancy, motion and transfer of power.  Connections to the great sailing ages in history, from the Polynesians exploring the Pacific, to Columbus’s crossing of the Atlantic, to the great whalers and galleons of Napoleonic Europe abound.  This project is the base for a great mix of artistic creativity and scientific inquiry.Drain Pipe Regatta

Boats can be made with nearly any craft material.  I have made origami boat challenges, foam board & skewer boats and water bottle boats.  Tweaks can be made with each regatta to reflect learning goals, materials or kids interests.  The Cub Scouts of America hold a raingutter regatta every year.  Scouts design small sail boats and race them down a 10 foot section of rain gutter.

Last time, my teacher bought a kit.  This time, I chose a simple design for this piece – a pine wedge cut from a 2×4, 1/4 inch dowels as … Continue reading STEM Project: The CO2 Rocket Car
