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.
ADVANTAGEOUS TO OUR DESIGN
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
ADVANTAGES TO OUR DESIGN
Step 6: How to Play
9-Square in the Air Rules
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.
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.
