The Fun Theory

A pyramid with 3 segments n line (or more if other glass colours are required to be separated) for clear, brown, green. Above these is a series of tubes, rotating about a centre axle, spaced at equal intervals. These are ‘loaded’ at the bottom arc, and then rotated to fire in the hole position at the top by a ship’s wheel. You 'load' glass into the tube. The wheel is then used to rotate it upright to the highest position over a protected hole in the container below. A mechanism (either auto or user-triggered) then releases this item to drop and fall into the container, at the centre of which is a spike projecting nearly to the top. The spike shatters and flings the glass out and around to fill the surrounding space with packed cullet.
