Events presided by Dr. S. Stonedahl
Guest appearances by: Dr. Trujilo and her students. Issac Schwantes.
What we did
    Caleb dropped buckets of sand on his foot.
    Measured K-Value of Silica sand. {K = 0.000555 m/s}
    Measured porosity of White Play Sand, again. {0.325123}

Minivans are important for moving research supplies...

   

Pool party... We didn't drown.

    Adjusted head difference on permeameter to a smaller distance.
    Began another test for the K-Value of the Silica sand.
    Returned to the Riverstone Group Incorporated and purchased some of their sand.

Filling Buckets  with sand

Don't worry we took turns (although there is no photo evidence)

 Measured the K-Value of Silica sand. {K = 0.000136 m/s}
    Took a lunch break.
    Brought in the sand from the Riverstone Group Incorporated.
    Measured the K-Value of Silica sand again. {K = 0.000106 m/s}
    Measured the porosity of Silica sand. {0.019608}
 
    Checked if fisher course filters could replace cotton
         nope.

   Ate sand (hardy-har-har [they were cookies])

   Checked apparatus for leaks
        ARE YOU SERIOUS??!!! (still leaks)
    We dried it and added a LOT of silicone to the outside all around the leaky corner.

What we will do
    Purchase pitchers and screens (1/4 inch and a couple mm)
    Make a strainer to filter the sand from the Riverstone Group.
    NOT go to subway
    start long process of filtering
