| 15 | * Impact test |
||
| 16 | ** The name of house guard in Höfðatorg is Albert S:6618467 |
||
| 17 | He said it will be no problem if we want to drop something of the roof for testing. The height of building is 74 m. Contact him one day before we want to do the test. |

| 25 | h3. Release Mechanism Test |
||
| 26 | |||
| 27 | Bogi, Örvar and Vikar made a test on the release mechanism. |
||
| 28 | The results from test: |
||
| 29 | * If it is windy the fabrics flap a lot and can damage the balloon. |
||
| 30 | * The coses did not fit together as we expected so we could not zip two fabric together. |
||
| 31 | * Have to find another way, f.x find large house and fill the balloon inside. |
