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.
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.
Pirate-themed get-togethers optional.

This week I designed and built a quick bike rack to store my young children’s custom bikes from two 2×6’s. You can check out the two bikes in the DIY Bike Build.
This project uses the table saw, miter saw and impact drill. A very basic design, it uses a number of my favorite “great-to-have” materials, such as 2 1/2” exterior wood screws and 2x pine for quick construction.

Yesterday, we completed a physics demonstration: The adjustable see-saw. This seesaw has holes drilled into the balancing beam, allowing students/users to experiment with the capabilities of numerous levers. You just shift its position along the beam and viola! Instantly, a foolish grin hits your face as you try to balance anew.
More pictures after the jump…
