Introduction: Marble Planets

About: I am a college student who loves inventing and creating. I like to do innovative and inexpensive projects.

I recently got interested in globes. Old fashioned globes, globes of the moon, and tiny globes. And I wondered, how does one make a globe? It turns out, all you need is a ball, glue, and some "gores." No, not like guts. A globe gore is just a spherical map that has been printed flat, which can then be cut and pasted onto a sphere.

Isn't our solar system beautiful? I decided I needed some mini planets. You can print the attached PDF and use with regular marbles, one mini marble, and one masher. (Marbles are not standardized, so it may not be a perfect fit.) Or, you can download the folder with the InDesign file and scale the images to the correct size for your spheres.

A Google image search of "globe gores" will come up with all kinds of gores, which you can scale to fit any sphere and print. The length of the gore needs to be the same as the circumference of the sphere. I measured the diameters of my spheres and calculated C=πd. If you want to make your own gores, you can upload a texture map (google "planet texture map") into this gore generator I found: https://www.winski.net/globus-projector/simplified/

Supplies

Color printer

Good scissors

Glue (Elmers is fine)

Marbles

Aluminum foil (optional, for the bases)

Step 1: Print the Gores

Use a good color printer.

Step 2: Cut Them Out

This is the fun/tedious part. Cut very carefully along the edges of the image.

Step 3: Glue It On

Apply a thin line of glue to the blank side of the gore. Wrap it around the marble and press. Spread glue on each of the open ends of the marble and press the tips of the gore down. Be careful not to smudge the ink with excess glue or glue on your fingers.

Step 4: Let It Dry

20 minutes should do it.

Step 5: Make a Display

Using aluminum foil, make little ring stands for your planets. You can check out my aluminum ring instructable here: https://www.instructables.com/id/Hammered-Aluminum-Foil-Rings/

Thanks for joining me! I hope you had as much fun as I did.

Two suggestions: If you want a smoother globe, print the gores on water-slide decal paper.
And "cup washers" from the hardware store make great stands.

I tried the water-slide decal paper. It was tricky to manage on small marbles, but there is probably a technique that would make it work.

Cup washers look perfect! Thanks for the suggestions.

Here we can see a great combination of astronomy and
woodworking in this project. The students make ornaments and souvenirs out of
wood and study the Solar System. We have completed the original project with
our own technological exercises on a lathe and finish using available
materials. Thanks to the authors of this great idea and to the Instructables
team for the opportunity to show our «masterpieces».

Beautiful planet jewelry! Using wood rather than marbles really makes this project more versatile. What a great way to combine art and science for your students!

Question 2 years ago on Step 5

Are they sturdy enough to play with?

Not really. They are more for display, though go ahead and play with them if you want :) I want to try using water-slide decal paper like gizmologist suggested. I'm guessing that would be more durable and waterproof. I'll let you know how it goes.

Absolutely LOVE your display around the T.A.R.D.I.S.!

I used to cover eggs with washi paper, and we'd lightly burnish the edges to make them flatter - with marbles it'd be easier as you won't crush any eggshells!

Oh, we'd use the back of a spoon to burnish

I like this. I wonder if soaking the paper in water or a watery glue mixture would help in the smoothness. I do like the lines, though, I'm not complaining. I use mod podge for most of my paper art and collaging.

I have had success with ink printers in the past by ironing the printed paper and letting it cool before using glue/modge podge on it. I had printed off some pirate maps and lined a cardboard pirates chest for a nautical themed bathroom. It hid the toilet paper under a tray filled with fake jewelry. The handle was a pirate's sword handle stuck right in the middle of the treasures and secured from beneath.

I tried using mod podge over top, and it did help smooth and make it shiny. It did start to bleed a little though, so soaking the paper probably wouldn't go well, unless you used a more stable ink.

I was thinking midge podge too so it would smoothen and (if glossy is used) make them shiney!

Sarahcd.... Great idea though! Never tried to work with gores' before! Thanks for the link too! The generator is a great find! Voted!
