DISCUSSION
This experiment was significant because it demonstrated Einstein's theory of special relativity. Structural testing was performed in which the 3D printed box was put in a vacuum chamber with a remotely operated pressure sensor see if the box would hold pressure. Structurally, the box held up to that impeccably, the box did not implode in anyway or crack under the high pressure. After that, a hole was drilled into the box and a pressure sensor was placed inside, and the box was placed in the vacuum chamber once again. Pressure was not held the first time, this was most likely due to the box being sealed with caulking which is watertight but not airtight. The pressure sensor test was repeated, but instead of caulking, hot glue and GOOP, which is “The strongest, most flexible all purpose adhesive ever created.” were used to seal the pieces of the box together. Once again it failed. However, pressure was lost at a much slower rate this trial. A final attempt was made in hopes to seal the microscopic holes; the box was dipped in a layer of acrylic resin. In the vacuum chamber the box lost pressure much more slowly, only reaching 6900 torr, which is only 100 torr under the pressure that causes electrical peaking.
Additional attempts to make the box truly airtight will be made prior to the payload launching. More structural testing was conducted. The whip test was performed; In which the payload frame was fastened to a rope and swung rapidly to simulate rapid acceleration of the payload. No hardware was damaged or moved when this test was performed, so it is believed that this test was considered successful. Impact integrity testing was conducted, the payload frame was kicked down the stairs multiple times. This was done in order to simulate the weather balloon popping and the payload falling from the atmosphere. The frame held up to the impact very well; there were no visible signs of trauma.
The data was so different at various altitudes because of special relativity. Muons tral so fast and have such a short lifetime. According to classical physics muons should not be able to reach Earth’s surface, yet they do reach the surface. So, it is know there are forces acting upon them such as length contraction and time dilation.
