How to Make a Watertight Wood Joint, Without Using Glue or Sealants

This woodworker shows how to create a gasket with just wood! Using the expansion of the wood he is able to create a water tight box without modern materials. via core77:

Unless you have experience with traditional boatbuilding or making traditional Japanese sake cups, you may not realize you can join two pieces of wood together–with no glue or sealant–in such a way as to make the joint watertight. Here master woodworker Frank Klausz reveals the trick taught to him by his grandfather, fabricating a helpful tool out of materials you probably have lying around:

It is indeed a clever technique, exploiting the behavior of both wood and water, and this is the first time I’ve seen it demonstrated.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
