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.
- Soldering iron.
- Glue gun.
- 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.
