1) The particles would bounce off of each other and change their shape frequently.

2) You can either rapidly cool the material or constantly stir up the material.  Cooling it rapidly causes the particles to cool so fast that they can't stick together and form clumps.  The stirring of the material causes the material to cool at its own pace but it breaks up large clumps of the material.

1) Grains are the small particles that make up solids.  When they don't fit together well they create fissures and imperfections in the solid that make the solid weaker.  The smaller the grains are however the fewer fissures there are and the stronger the solid becomes.

2) In order to reduce imperfections there are a few methods that create smaller particles one is the Czochralski Growth method.  It is when a rod is dipped in a high grade silicon and then twisted and pulled out and cooled.  The silicon fills the imperfections in the metal and makes it stronger.

Invention: Explosives

Our idea is to create an explosive powder so fine that it allows for a larger explosion for a smaller amount of powder.

This is the orientation and general layout of the diffraction grating and the placement of those diffractions, we figured out that the spacing between the dots was attributed to the distances between the lines and estimated accordingly

2) Red- 1cm and 1.5cm on the respective diffraction gratings
Green - 1cm and 1.25cm on the respective diffraction gratings
160nm is the distance between the lines and 60 nm is the thickness of the lines
