PHiZZ stands for pentagon-hexagon zig-zag unit and was created by Thomas Hull. You can check out his work here. Thomas Hull explains how to fold the model and assemble the balls but there is a lot of information there so I decided to make an Instructable that might be a different way to learn this awesome system.

The PHiZZ unit has quickly become one of my favorite modular origami units because of the simplicity and potential to make many different size balls. There's also a lot of math/geometry stuff that you can get into by studying these that Thomas Hull explains on his site.

I plan on making Instructables for all the PHiZZ balls that I've made so far up to a 360 unit one. I also plan on adding some videos and other fun stuff too so be sure to keep an eye out for those.

Step 1: Materials

To make a PHIZZ ball you will need 30 pieces of square paper.

Step 2: Folding the Unit

1. Start with the paper colored side up and fold in half.

2. Fold one layer to meet the middle crease so that the colored sides now show again.

3. Flip the unit over.

4. Fold the layer to meet the middle crease.

5. Fold the left corner down to meet the bottom.

6. Fold the strip to the right down to line up with the edge of the corner that was just folded.

7. Fold the strip up, using the bottom as a guide for creasing.

8. Fold the strip down, on a diagonal, lining up with the bottom.

9. Flip the unit over.

10. Fold the left corner down to line up with the bottom and last fold made.

11. The unit is now done, open it up by unfolding the zig-zags so that the paper is in a strip 1/4 the size of the original size.

Now make 29 more.

Step 3: Assembly & Preview

Once you have 30 units it's time to assemble them into a ball.

Start by insetting Piece 2 into Piece 1, as in the second picture. You'll notice that the crease lines will match up to lock it in a little.

Open the pocket on Piece 2 so that Piece 3 can be tucked into it, fifth picture.

Once Piece 3 has been tucked into Piece 2, the pocket on Piece 3 will need to be opened so Piece 1 and be tucked inside, as shown in the seventh picture.

The three pieces together will form a triangular peak. Keep adding more units in this fashion to create more triangular peaks. Eventually a ring will start to form, this is a good thing. Keep forming the ring until you have a pentagon shape as shown. To make the ball you just need to keep adding onto this ring to make more pentagon rings and eventually a ball will form.

If you get confused feel free to comment and I'll try to explain it. I'm sure once I add the how-to video it will be more clear.

Below is a video of a larger PHiZZ ball that I made and will cover soon in another Instructable.

this isnt origami <br>Origami from ori meaning &quot;folding&quot;, and kami meaning &quot;paper&quot; is the traditional Japanese art of paper folding
<p>hey, sorry, you are incorrect, this involves no cutting (that would be kirigami), only squrare sheets of paper, with no glue. it's modular.</p><p>note that this is real modular, meaning the modules are all of the same type.(if the modules are reversed, such as in the shruikan, it still counts.) do not confuse with chinese modular or 3d origami!</p>
If I may add... 3 years later. Technically she is folding and using paper. And making it into something, all without the use of anything else. No glue, no tape, no staples. Just paper and folding... Origami is the correct term. Modular origami to be exact. Thanks.
It's modular origami.
<p>it's called a </p>Rhombicosidodecahedron
WHO HAS 30 PIECES OF PAPER???!!!....do sticky notes work?
I use sticky notes all the time b/c of my laziness. It'll work
<p>Yes, they do work.</p>
Try it and find out (and post a picture here)! I've used sticky notes before but prefer using thinner origami paper.
Christmas tree star! Tada! I had such a frustrating time just finding a pattern online that i could see the steps. This guide was easy to follow and the images of the steps were clear to follow.
<p>30 is a rather small amount when you have used 270 pieces of paper. Also you can get 4 pieces of square paper that are the perfect size out of an A4 piece of paper. Juts make it into a square and make 4 other squares.</p>
<p>That is TO much paper. I use less to do assignments</p>
<p>made a huge one with scrap paper, thanks for the instructions!</p>
my first origami. thanks!
<p>your first one?! HOLY COW</p>
nice one there
hard work of 2:30 hours...<br>ffoooo....
<p>Hi, I made my PHiZZ ball. But I made it hexagonal. and I used 30 pieces but its not coming together, i dont know what to do.</p>
I used red orange and blue and they look really good
Very cool, it looks great!
stupid question but how many side does your example phizz ball have when you finished it?
Actually that's a really good question. <br /> <br />It has 12 sets of pentagonal faces. <br /> <br />It's basically a dodecahedron but made up of triangular edges. The shape might have a different name though, I'm not sure.
(BTW, your linke out to Thomas Hull's work is broken. I couldn't find another link that seems to be written by Tom Hull.)
Yes, the site seems to come and go in terms of availability but I'm going to leave it for citing purposes.
Hi there Sherry, very nice instructable. You look like you might be interested in <a href="https://www.instructables.com/id/Make-the-Raibow-PHiZZ-Origami-Buckyball/ :" rel="nofollow">this related one</a>&nbsp;I just posted&nbsp;:-)<br> <br> -Caleb<br> <br>
Now make 29 more. <br> <br>Well thats very straightforward
;)
That was fun :D You must have great dexterity to make those small ones. I used 75mm squares and it ended up much larger than yours.
Hi, can you build on how to finish this thing? i tried it and now i have an ugly oval thing...
Could that all the openings are only pentagons (5 sides). If it's shaped weird you probably have a 4 sided and 6 sided face somewhere.
awesome.....
cool! <br>i love origami. <br>This is great! and thank for sharing
cool one lolz
Super cooolll........... thanx for sharing.. :D
cool! <br>i love origami. <br>This is great!
Wow! This is spectacular! I'm going to attempt it right now.
Thanks for the instructions! <br> <br>
Awesome! Thanks for making one and sharing a picture. Now I'm motivated to post the larger ones haha, keep an eye out.
Wow that's cool to see how it was made. Although, it looks tedious to complete. Thank you for sharing .
Cool and clear &ndash;&nbsp;thanks for posting!
