## Introduction: 9 Square in the Air

A couple of teachers wanted to bring the typical youth group activity to life in the middle school. So we set out to redesign the game so we can have more kids playing at a fraction of the cost.

## Step 1: Typical 9 Square in the Air

The game is a 9 square that sits anywhere from 6 to 8 feet in the air depending on size and age of those who are playing.

The pieces needed are nothing more than connector joints and pipes.

Online the connector joints cost \$339 and the the complete kit runs \$799. A large investment for any church or school for a game that only allows 9 students to play at a time.

## Step 2: Problems With PVC Pipes

The first design problem we encountered is there is no PVC joint that has 5 connectors. This meant we would have to find a way to connect our pipes differently if we were going to design our own.

Our solution was to take the vertical support and move to the midpoint on each square. This idea would solve two problems. The first of which is now we did not need 5 piece connector. We will discuss the other issued solved in a later steps.

## Step 3: Size Vs Height

Knowing the squares themselves would be cut to put support pieces in to address the connector joint in the previous step, we looked at the access we had to PVC pipe.

We decided to go with 2 in pvc pipes that came in lengths of 10 ft.

Question is how big of square did we want, and what height?

We decide on 5 ft by 5 ft squares and that would be 7.5 ft high. These measurements saved us many cuts, and saved us on wasted PVC pipe, remember we are teachers and we are on a budget. We cut the 10 ft pipes into 7.5 and 2.5 pieces.

7.5 ft pieces serve as the support

2.5 ft pieces are the squares(with the connector joints we pick up a few more inches so the square is a little bit bigger that 5ft by 5 ft.

So we have a 25 sq ft box at a height of 7.5 ft. Good size for our aged range of 12-14 years old.

One size of pipe to order, one size of cut to make, and the build only works with 2 different lengths, either its a vertical 7.5 ft piece support, or its 2.5 ft. square piece. No confusion on the build.

We had to count up our pieces and arrived at:

24 7.5 ft pieces

48 2.5 ft pieces

A total of 30 , 10 foot pvc pipes will be needed for on 9 square in the Air game.

PVC 2" x 10 ft pipe cost \$4.49 for a total cost on pipes \$134.70 in PVC Pipe.

Now its time to take on the connector joints.

## Step 4: The Build

Working from the inside out we began to piece our design together. We decided to add bushings onto the end of the vertical poles to provide extra grip as well as protection to the floor. We built the squares first and then with a few extra hands we were able to lift and support the square with 7.5 ft vertical poles. Its not a bad idea to glue a few of the connector joints but you will want to consider storage.

## Step 5: Final Cost

30 PVC pipes 2in x 10ft at \$4.49 per piece Total cost of pvc pipe \$134.70

32 2in T connector joints at \$2.48 per piece Total cost of T joints \$79.36

4 2in 90 degrees elbows at \$.95 per piece Total cost of elbow joints \$3.80

24 2in Bushing at \$0.84 per piece Total cost of bushing \$20.16

FINAL COST : \$238.02

Online cost : \$799.00

Savings : \$560.98

## Step 6: How to Play

9-Square in the Air Rules

KING VERSION

1. The “king” serves the ball from the center square to any other square by hitting the ball up and out of the top of the center game square.

2. Players must return the ball to another player’s square.

3. If a player fails to return the ball to another player’s square, that player is out.

4. A double hit results in elimination.

5. During game play, players are not allowed to touch the game structure. Touching the game structure results in elimination.

6. When a player is out, they leave their square and move to the end of the line. The other players advance to fill the square of the player who just got out.

TEAM VERSION

Players will compete 4 on 5 where team mates are staggered in a checkered pattern. Play similar to rally scoring in volleyball, players try and prevent the ball from landing in their square. The ball can be set into play by the team that scored last, or alternate turns. Game ends when one team reaches a set point limit. More players is not necessarily an advantage as it means you have more squares to cover. This style leads to setting teammates up to score points by incorporating passing between players.

I'm unsure what a bushing is. Can someone post a picture of the bushing so I know what to look for?

I have made approx 200 9-square games Here is how i made them. My cost is about \$100 cheaper and we use the large \$2.50 walmat ball. You can get all the parts from Home depot online. See part #s.

My son wants to build this game for our elementary school as an Eagle project. Can you please email me the specifics? It would be so appreciated!! Thank you!
jafisher@wsd.net

Can you make a shareable link with the parts list?

Hi there, I also cannot make out the part numbers from the screen shot, if you could also shoot me an email with all the details that would be awesome, so I can also copy down part numbers; hannah.henter@gmail.com Thank you! Hannah.

Thanks for this but I cant quite make out the part numbers from your screen shot. Any chance you can send me a better image of that so I can copy down those part numbers?

Anyone have a good idea on how to store it?!?!?!

i'm building this, this weekend. was thinking about using a rolling trash can? like you can buy at walmart. and some bungie straps to hold the long legs together...IDK. we'll see.

I went down to the local thrift shop and bought some heavy material, like window drapes. I made 2 bags. One bag for the 5' pieces and 1 bag for the 6' pieces. I put a drawstring on the top and it has held up for quite a few years.

keep it outside of your house

I bought upright drawstring christmas tree storage bags. They are sturdy and have handles. Largest i could find was 60" so the pvc sticks out the top but works great. I also bought a mesh sports bag to keep the connectors and ball in. Then i had an old metal upright shopping cart laying around that they fit perfectly in so i can roll them in and out.

How has your design held up? Wondering if the quality is as good as the original.

Storing the 7.5 foot pipes seems like a challenge. I'm thinking of making the verticals out of two pieces, 5' + 2.5', so there are no pieces longer than 5'. Leave off the 2.5' and you have a shorter construction that littler kids can use. Also, I like the idea of using the 5-way connectors from Amazon, so all the horizontal pieces can be 5'. Buy 5' pipes and you only have 12 cuts to get the 24 2.5' pieces.
