Find the right material to create the prototype :
So I spend yesterday running from one store to other, trying to figure out how I can build this object.
I was thinking of using plastic bags to create the inflate ball ( reusing materials) but I decided to change and use a ball already made, like a beach ball to create this prototype. I went to Canal Plastics and bought 2 half transparent circles made of plastic that was ideal to build this prototype since I had to put the labyrinth of tubes inside the ball.
To create the labyrinth, I bought plastic cables that is used to protect wires and with sculpture wire inside I shaped them to create the desire effect of a labyrinth.

One of the most difficult part was to decide how to create the holes on the plastic ball, in order to create the inputs and outputs and also to put each individual tube out of the ball. First I thought in using the drill but I decided to try using the solder iron to "burn" the plastic and this way create a hole. Yes...the soldering iron is dead..maybe i can use it again to burn something else..but it worked perfect to create the holes.
Here is the result of this experiment:
