Second Semester Changes: As noted in the power point slide attached above (this has been slimmed down do to the size of the original file) , some design changes made included a switch from a hypodermic needle to a glass pipette manually drawn out and the use of a linear actuator for force mechanism.
The following YouTube videos provide a general basis of the crystal structure and effects that were able to be modeled.

We used a Plexiglas cutting tool where we scored the Plexiglas several times, which made what we call a “brake line.” We then bent the Plexiglas along the brake line, which allowed for a clean linear brake. We were not able to use this method for some of the pieces, such as the sidewalls. For those, we asked a professor in the Loyola Physics department, Howard Moore, to help us cut them. After we had all the pieces cut we sanded down the edges in order to make them smooth and to ensure a solid connection between them. Finally, we used an acrylic cement called Weld-On© to weld the pieces together. And last, but certainly not least, we used a silicon sealant to ensure that there would be no leakage.

0-200 psi (0.7 – 2.8 psi needed)
Tygon Tubing
Inner diameter = 5/16”
Wall thickness = 1/16”
Hypodermic needle
22 gauge: inner diameter = 0.413 mm
Layout
The compressor (producing minimal pressure) will feed to the compressor hose, which also has a pressure adjustment
valve, which will then go to an in-line pressure gage. After the pressure gage, we will attach the Tygon tubing using a
hose clamp which will then lead to the plastic syringe neck and then finally to the hypodermic needle.
Soap Solution
added 293 mL of pure glycerin. We then diluted this solution with water two to three times and let the solution settle. We had our
final solution after we separated the clear liquid from the sediment.
