Giant Magnetic Sticks Set




Introduction: Giant Magnetic Sticks Set

About: I like to make things. Art, inventions, tools, ukuleles, etc...

These sticks and balls are a scaled up version of the many small sticks and balls sets you’ve probably seen before. It’s fun to be able to go inside the structures you build. I made sure each stick would have a north and a south pole. And later I marked them with white tape which is helpful when building. If a ball gets too many white or black ends on it they start to not stick very well. So the marking helps to mix it up. It’s not necessary, but nice. I found these tubes at a local surplus store so the length is arbitrary. You can obviously make them whatever size you want.


24 or more ½” OD x 35” fiberglass tubes

100 or more disk magnets ⅜”x 3/32”

20 or more ⅞” diameter steel ball bearings

hot glue

white tape

Step 1: Mark One End of the Tubes

Mark one end of the tubes with some white tape.

Step 2: Mark the Polarity of Your Magnets

Mark the polarity of your magnets with a sharpie. A black dot is all you need. The black dotted ends will face the black (unmarked) end of the sticks. The unmarked sides of the magnets will face the white ends.

Step 3: Hot Glue Magnets Into the Tubes

Hot glue two magnets into each end of the tube using a ball to set the depth while the glue cools as shown. Once cool pick off the extra glue squeeze out.

Step 4: Try Them Out!

Kids might like to clip sheets to their structures to enclose the space. Have fun.

    What are the fiberglass tubes originally used for? I'm not seeing them anywhere online or in hardware stores. Maybe knowing the original purpose would help direct my search. If you have any suggestions of where to find them, that would be great!

    I have always wondered what they were for, too. I got them at a surplus store years ago. So sorry, I don't know. I looked online as well and came up with nothing other than expensive carbon fiber tubes.

    Excellent very good to stimulate any child/adults creative mind when as a child we used two chairs and a sheet to create a secret den /tent.If there was washable tear resistant sections triangular,square etc that the tubes could be threaded through even more scope.even a castle maybe or train.As to the tubing plumbing section has very strong long lengths easy to to the magnets make sure you use the correct glue so there is no fear of the magnets been dislodged or swallowed some magnetic toys have been blamed for children's deaths I also see several children in the neighbour hood having your version and playing together and joing sets to make that castle I was thinking of also get them away from computer games and outside in the fresh air social distacing relaxed of cource .
