This Bubble Machine From Trash is a Do It Yourself instructable designed for those individuals with sensory processing disorder and learning disabilities to create a bubble Machine from trash. The concept is simple. A disk full of holes will rotate to alternatively dive into a bubble solution and go in front of a fan. It will create bubbles.

Technical Specifications: 

Step One: Gather materials.

  • Two plastic bottles.
  • Some cardboard.
  • 1 wine cork.
  • 1 CD-ROM or DVD.
  • Gear Direct Current motor from a broken electric razor (about 100 Revolutions Per Minute).
  • Direct Current motor from a broken remote-control car (At least 5000 Revolutions Per Minute).
  • Battery holder from a broken remote-control car.
  • Tools:
  • Soldering iron.
  • Pliers.
  • Drill.
  • Glue gun.
  • Scissors.
  • Utility knife.

Step 2: Cardboard Support.

  • The first step is to make the structure of the bubble machine using cardboard.
  • The size of this structure will depend on the size of the small plastic bottle that will be used as a trough.
  • Cut a rectangle in strong cardboard.
  • The length should be the size of a small plastic bottle.
  • The width should be 3 times the width of a small plastic bottle.
  • Then make a rectangle parallelepiped out of cardboard.
  • The length should half the size of a small plastic bottle.
  • The width should be the width of a small plastic bottle.
  • The height should be the diameter of a small plastic bottle.
  • Finally, Glue the parallelepiped in the middle of the cardboard rectangle

Step 3: Trough.

  • The trough of the bubble machine is made from a plastic bottle.
  • Cut a rectangle on the side of a plastic bottle. The hole should be a little bigger than the diameter of a Compact Disc Read-Only Memory.
  • Then glue the plastic bottle on the cardboard structure.
  • Step 4: Bubble Ring.
  • Next, the user will need something that will rotate through the trough to pick up the bubble liquid. This example uses a Digital Versatile Disc.
  • Make 12 holes in a Digital Versatile Disc using a soldering iron. Each hole should be as close as possible from the exterior of the Digital Versatile Disc.
  • The heat of the soldering iron will result in holes that the user can't make with a drill.

Step 5: Make the Bubble Ring Move.

  • Next step is to build something to spin your bubble ring in the trough.
  • This example uses a gear motor that comes from a remote control car.
  • Glue the Digital Versatile Disc to the motor using a plastic cap.
  • Then glue the motor on the cardboard structure. The Digital Versatile Disc must go inside the plastic bottle hole.

Step 6: Fan.

  • The fan is made from a plastic bottle and a motor. This motor comes from a broken electric shaver. The user can use any motor that spin at 5000 Revolutions Per Minute or more.
  • First cut a small rectangle from a plastic bottle and fold it to form a propeller.
  • Then insert the propeller on the motor axis.
  • Then glue this fan on the cardboard structure using a wine cork to adjust the height.

Step 7: Power.

  • Both motors will need electrical energy to work.
  • Connect a battery holder to the two motors and glue it on the cardboard structure. As motors are 3V two AAA battery can be used.

Step 8: Bubble Solution.

  • The bubble solution is made from 1/2 dishwashing liquid and 1/2 water. This 50:50 mix works well but the user can add a spoon of glycerine for stronger bubbles.

Step 9: Enjoy the Video (below).

  • This video summarizes all the steps then shows the final result with bubbles.
