| MASS: |
6.311 kg (~12.69 lbs.) |
| DIAMETER: |
22.08cm (~8.7") for a circumference of 69.4cm (~27.3") |
| VOLUME: |
5632.5 cm3 |
| DENSITY: |
1.121 g/cm3 |
| TOPOLOGY: |
Singly-connected 3-dimensional sphere. |
NUMBER
OF BANDS: |
~6200 based on a mass ratio determination (1.03 g/band).
I estimate that only 3.3x1034 more rubberbands are necessary to turn Megaball
into a neutron star.
|
| STORED ENERGY: |
~4542 J estimated using a measured value of 0.64 J per band
and spring constant of 8.73 N/m. Megaball would power a 60W lightbulb for
~75 s. |
| TOTAL ENERGY: |
~1016 J.
If the ball's mass were converted directly into energy with 100%
efficiency, it would power a 60W lightbulb for 1016 s, or 300
million years. |
| INTERNAL PRESSURE: |
67.57 MegaPascals (~670 atmospheres, or four miles of water)
note that this measurement is almost impossible to estimate with any accuracy. |
| HIGHEST BOUNCE: |
When dropped from the 10th floor of my building,
Megaball bounced back up approximately 20 meters (~60'). |
| LOUDEST SOUND: |
When bounced in the bathroom of the 7th floor of my building, the low frequency thud could
be felt and heard clearly on 2nd floor.
|
| AGE: |
Began in October of 1993, so almost 6 years. |
