The
apparatus is made of a
clear tube, that is 75cm long and at a 20º incline to a 20 gallon
container of saturated salt water, with a flat, smooth bottom.
The
bottom needs to be smooth so that there is as little friction as
possible and that there is not a change in the basal friction and the
model runs. To start put a single triple batch of flubber into
the tubs as flat and thin as possible. Then add another triple
batch of flubber behind that is also flat and that is at the same total
height. Then another triple batch needs to be added in smaller
equal increments at the top of the tube behind the rest of the flubber
and also trying to keep the thickness then same throughout the entire
experiment. This is done so that there can be a constant flux and
driving force of flubber in the system. Then the first sets of
flubber need to be gridded using small beads that are light and
colorful so that they can be seen in high resolution pictures.
Gridding should then be done as often as needed so that data points are
continuously able to be found throughout the run. Then the
cutting off, calving events are done at the same location so that
amount of flubber taken out of the system can be measured so that the
can in mass is known.
The model is then let run with taking pictures every 5 minutes and
adding additional flubber after each picture and adding more beads to
the added flubber so that analysis can be done with the pictures that
are taken. This experiment takes 2 to 3 hours to run.
To have this experiment
work the density of the saltwater must be as high as possible, to know
if the density of the salt water is high enough so that the flubber
floats
between 5% and 10% of its volume.
