Wrap the magnets with tape.

Prepare the bolt and washers

Wrap the straw with 32-gauge magnetic copper wire.
Leave about 6 inches on either end of the wire free.

Tape the wire leads in place.

Burn the enamel off the tips.

 

It didn’t work. Some factors to consider for next time:

  • More magnets?
  • Larger radius of straw?
  • Lid optimized for vibration–try a balloon?
