Introduction: Gee-haw Whammy Diddle

About: Hi, I'm Yaron, A proud father of 3, A software engineer by trade and a creator by DNA. My love for building things started at an early age working with my dad over the summers, now this love fills my free time…

This is my third instructable in my toys category ("Floating Pingpong Toy", "Solar Plane").

"Gee-Haw whammy diddle" is a toy that not only has this great playful name, it also is magical by how it works!

It's simplicity and the physics behind it, made me curious to the point i had to build one,

This is a quick instructable anyone can finish in 30 minutes!!!

Supplies:

Supplies:

  • Wood stick
  • nail

Tools:

  • saw
  • drill (optional)

Step 1: Sticks

For this toy we need two sticks:

Main one with notches and a plane one,

I choose a stick with 1.5cm in diameter and 20cm long and for the second i cut a stick of 15cm long.

Step 2: Notches

The notches should be located at the top of the stick, about 10cm, where you should leave enough space to hold the stick, bottom line: 8cm (handle) , 10cm (notches), 2cm (blank).

With a hand saw, cut notches in 30-45 degrees as shown in the picture.

Step 3: Propeller

I used a scrap of thin wood 5cm long, marked the middle and drilled a hole.

IMPORTANT: the hole should be twice larger than the nail you are using(in diameter).

Step 4: Play!

Hold the "handle" firmly to direct the vibration to the propeller and with a second stick rub the notches.

Enjoy!

Challenge:

Try controlling the direction it spins...

    My dad showed me how to make these out of rose bush stems when I was a kid. They are a treat for the little ones and always fun to make. It's cool if you have a y shaped branch and can get them to spin in opposite directions...

    Thank You!

    great job! make one a little longer and taper the end, then you've made a tool that will make earthworms come out. you put the tapered end in the ground and rub the grooves with the plain stick.

    Donkey's years old. The other one was a bull roarer or perhaps the folded brown paper and cardboard thunderclap. Better than all the plastic rubbish.
