Bottles, razor knife, and razor saw

One bisected bottle
The second bottle was bisected by cutting the thick bottom first with the hope that the structure would be easier to handle for the cutting. Cutting the bottom first was easier than cutting the sides first but after cutting apart two bottles a motorized saw will be used to cut the 2-liter bottles which will be used for the wind turbines. Learning on the 1-liter bottles was a good choice since the bottles will now be cut uniformly. Pictures of the small 1-liter bottles were made after putting the bottles into the plastic support pieces to give an idea of the desired shape.
