Scribbling machines are motorized contraptions that move in unusual ways and leave a mark to trace their paths. They are made from simple materials and set in motion by a vibrating offset motor causing them to bounce, spin, bump and move in interesting ways.

Step 1: Materials

Collect these things:

  • 1.5-3.0 volt motor [link]
    Note: You can find motors in all sorts of mechanical toys and common household objects; we encourage you to salvage one instead of buying it!
  • AA battery
  • A piece of hot melt glue stick
  • Broccoli band (thick rubber bands used for produce)
  • Markers
  • Recyclable container such as a strawberry basket or yogurt cup
  • Masking tape
  • Paper for testing

Some other helpful materials:

Clothespins; Popsicle sticks; wood skewer sticks; pipe cleaners; wire; nuts, washers, or other small weights; wire stripper; scissors; small screwdriver; googly eyes.

<p>I made this activity with 3 groups of 16 kids placed in pairs. It was a great success, they I used water bottles and elastics instead of tape. However, in compare of the prototypes showed in the video, the machines they made were a little to heavy considering the power of the motor. I recommend to follow the suggestions on below! Thank you for this great idea. Your site is just amazing for the fun activity hunter that I am!</p>
