mobile is a type of kinetic sculpture constructed to take advantage of the principle of equilibrium. It consists of a number of rods, from which weighted objects or further rods hang. The objects hanging from the rods balance each other, so that the rods remain more or less horizontal.

 Alexander Calder 

Artist Alexander Calder was the originator of the mobile. By suspending forms that move with the flow of air, Calder revolutionized sculpture. It was Marcel Duchamp who dubbed these works ‘mobiles”

Scavenger hunt

Collect items that are no longer needed and match these descriptive clues:

Game/puzzle pieces from old a discarded games and puzzles

Old deck of cards

Construction/colored paper, left over greeting cards from Christmas past

Pine cones, acorns, pieces of drift wood

Broken pieces of costume jewelry

Empty food cans (washed and dried)

Cardboard rolls from toilet paper and paper towels

Anything you think that might flow freely with the air

What you need:

String, ribbon, fishing line (you choose what works best for the objects you are using)

Tree branches, dowel sticks, heavy cardboard, old metal

clothes hangers (something to use for hanging your objects from, cut into different lengths)

Glue or hot glue

Hole punch, pliers used to bend wire if your using the hangers

Paints (if you want to paint your objects)


  1. Collect 6-10 objects that are about the same weight as one another. I used cat food can tops
  2. Tie fishing line/ string to each object, and leave about 6 inches of string left over.
  3. Start at the bottom level of your mobile, and tie one of your objects to each end of a stick / or whatever you choose to use (wire hanger, branches etc)
  4. Tie a piece of fishing line/string to the middle of the stick that has the objects tied to it. Find the center of balance by holding the string up and letting the stick hang. Move the string around the center of the stick until the stick is balanced then glue string in place.
  5. Connect the loose string to the middle of another stick.
  6. Add objects to the ends of this second stick and repeat step 4.
  7. Keep working your way up the mobile until you think it’s finished.
  8. Now, all you need to do is hang it up and watch it turn in the breeze.

When you are done with your mobile you can bring it to the library to display it or send photos to to have them put on our web site. All mobiles are due July 31st. Prizes will be awarded for the most creative, most unusual and most mobile.
