Points Discussed:

• Presented ideas for seals on test tubes
• First idea - pizza
• A full lid that rest 1/16th above the test tubes
• Pros
• Simplistic design?
• No hooks
• Cons
• Limited motion of mixing?
• Second Idea
• Similar to old design 
• No center pole
• Lid rotates to expose 1 tube, as needed
• Pro
• No hook aka no binding
• Good seal
• Con
• Seal potentially may be overkill/unnecessary (may be toned down so that it’s just a cover)

• Funnel top + First Idea 

• Funnel top helps dirt stay in the test tube even more
• Pros
• All passive
• Secure
• Cons 
• potentially limits flow
• Needs more testing

NOTE __ CENTRIFUGE IS MIXER OFFICIAL NAME CHANGE??????? <_> >.<

Shovel 

• Old Shovel
• Did not collect enough dirt
• New shovel - double shovel
• Theoretically collects more dirt, and also supposedly drops dirt more efficiently/smoothly
• Mount bearings to make motion more smooth
• Shovel is likely too big (when considering the amount of dirt that would be picked up)
• Difficult three D print
• Prototype needed
• Linkages need to be tested, shovel can always be changed
• Moment calculating needed

• Chain for elevator mechanism or Tensioning Belt
• Need a camera on mech to see test tubes to analyze
