Step 1: Materials and tools
Hot wire for cutting foam (in this case used for cutting the bottles)
Some medite to make couple of jig
Hole saw drill bit that would make a hole just big enough for the mouth of the soda bottles
safety mask to protect yourself from the toxic fume when cutting the bottles with hot wire cutter
Step 2: Cut the bottles
Cut as many bottles as you wish.
You will end up with four parts, the mouth, upper, middle and bottom.
Flatten the bottle, put it in jig 2 and drill the four holes.
The middle part of the bottle once pressed and flattened will be the building block of the plane, the mouth becomes the connector between individual building block.
Do not throw the upper and bottom part of the bottle, they are essential for the structural integrity of the plane.
Step 3: Assembly
The assembling of one bottle to another is quite self explanatory.
overlap the flatten and drilled , put the mouth of bottle through the hole, screw the cap on.
to stand the plane up, our idea was to create a pocket in the plane so that it can be filled with the upper and bottom part of the bottle hence creating wider base.
