Testing Subjects: Wick Materials

Methodology
  1. Cut the wooden bar into two bars of 36" and two 6" of length
  2. With the use of a drill, drill bit and screws, attach each 36"-long bar to one of the 6" long bar, so that there smaller bars provide support and thus the long bar can stand. (See Figure 1)
  3. Make a hole in each bar near the edge, opposite to the 6" bar attachment. The hole should be roughly bigger than 1/4", big enough for the rod to slide through the holes. Make sure the holes are at the same level, to keep to rod horizontal.
  4. Stand 36"-long bars, separated by roughly 40".
  5. Insert rod through holes.
  6. Fill basins with 1500 ml of the contaminated water sample
  7. Set basins on the floor, underneath rod.
  8. Hang wick materials on rod. Make sure the materials sit on the bottom of the respective basins
Running the experiment
  1. Record the experiment starting time: right after all the wicking materials are sitting on basing
  2. Measure the average height reached by the water in each wick material.
  3. Repeat step 2 every hours, until a total of 4 samples are collected.
  4. Record data.
  5. After all four samples are collected remove materials from basins and weight water in each basin to find the amount of water absorbed per material.
