What is an Icosahedron?

"In geometry, an icosahedron is a regular polyhedron with 20 identical equilateral triangular faces, 30 edges and 12 vertices. It is one of the five Platonic solids." - Wikipedia

Why should I build an Icosahedron?

- To get inspiration. Trust me. Once you have started, a million creative ideas start to pop up in your head!

NOTE:

To build the icosahedron you need to see all the images. To see all the images, you need to join Instructables.com

Step 2: Sort The Sticks

Work with the good stuff.

Go through your pile of sticks, and take out sticks that look ugly.

Bent, broken, dirty, stained, rough, all those you put aside.

Step 3: Basic Setup

This is the basic building block that we will use.

A Triangle.

Have fun. Glue a bunch.

We'll need twenty of these. (Icos = twenty)

Do a few more. You really can have fun with these triangles.

Just make sure they are all alike. A flipped one won't look so good.

Step 4: Have Fun While You Can

Now, didn't I tell you that you'd have fun?

Grab'em, stack'em, break'em... No. Don't break'em.

Have as much fun as you want.

Step 6: Lift It Up!

Time to LIFT!

Carefully lift up the center of the figure. The two "loose" corners should meet.

Tape under the two sticks that you matched together.

Make sure you put the structure on a flat surface. Then you can glue all the joints.

Step 7: Think!

The next steps are a bit hard to explain. It's the same building process, but complicated to explain.

Take a look at what you just created. The tip of it is a vertex. It is the point where five triangle tips join. It is important for the next steps that you only put five triangle tips in each vertex.

Now go ahead and join trianges with tape, in groups of four, three, and three. In a straight line.

Step 10: Make a Lid

Make a lid like the first one, using five triangles.

Place it on a flat surface before gluing it.

Step 11: Finish The Icosahedron

Join the main structure with the lid. There are five vertices (plural of vertex) to glue this time. You don't need to tape this time.

If your edges don't join perfectly, like in the third picture, melt the smaller joints, gently pull the triangle tips together, and glue the vertex.

When you have glued all the vertexes, and the glue has hardened, remove all the tape strips from the inside.

Also clean up all the silicon threads from the glue.

Step 12: You're done!

If you have followed all the steps correctly, you should have an Icosahedron.

Feel free to remix the idea, by adding your own decoration. Maybe paint it, varnish it, cover it with paper, put a LED in it, etc.

I like the look of the little candle inside it, but fire and wood don't go well together. Neither do heat and hot glue. But it still looks cool!

Hi, i think your instructable is really fun! After I saw it I immediately made one for myself, then I painted it, it'is really nice, so I wanted to share with you the result!

Again, congraturations!

Thanks for sharing! Really nice work!

Thanks it's soo cool! I made it! It was a little harder than I thought but it was worth it! It takes 15 triangles and a lot of glue!

WOW! Nice idea. Also good photography, pretty rare on instructables :P
colorex (author) 2 years ago
Awesome. I've been featured in lot's of places. Not significant places, but still!

Just search "Popsicle Stick Icosahedron" on google and you'll see!
Very cool. I love things that are simple to make, don't involve power tools and can be done relatively quickly but look elegant. Great job!

IT WOULD BE REALLY COOL IF YOU PAINTED IT THEN PUT PICTURES INSIDE EACH TRIANGLE.
colorex (author)  lullerfly862 years ago
You're right. But I don't have the patience... LOL

i once made one of these with cardboard, also one with cardboard that i cut out and put platic, and i hung it like a lamp... it wasnt very sturdy though. i must try this!
colorex (author)  evacooper2 years ago
This one is indeed very sturdy. I dropped it once, 3 ft high, still intact.
I made this but added tissue paper on all the faces. You could use different colors on each face if you wanted. I also used a "flameless" tea light candle to avoid burning my house down!

cool. gotta love platonic solids... (platonically of course)

Would it work to make 4 of the pentagonal "lids" and stick em together?
colorex (author)  geeezer3 years ago
Nope. You can make three lids, but the fourth wont fit anywhere. Nice play on words, there!

I made something similar SO long ago in middle school art class. We made a "stellated icosahedron", which is the addition of spikes that come out from each triangle on the surface of the icosahedron. I had that thing hanging from my ceiling for years.

We used small diameter straws (think cocktail straws), strung together with strong thread, which made it more or less impossible to see how it was held together and also gave it some flex.

To "stellate" the initial icosahedron shape, string longer sections of straw off of each intersection and then bring their tips together, eventually making the whole thing a 3D star...

Thanks for this 'ible, brings back fun memories!
colorex (author)  mispel3 years ago
Yeah basically I could do the same thing with 180 sticks more. You just build a pyramid on each of the faces.
I did think about that, but I had only 100 sticks...

I'm glad you like it :)
mispel mispel3 years ago
Oh yeah, and a tip for assembling this way is to use a heavy needle to string the thread through the straws. That way it just drops through quickly and easily...
