2. understading buoyancy

The idea is to make sure that the frame having the stability that we need. The bottle is been put at the top of the frame to test the ideal buoyancy. We experiment it at IIUM swimming pool with 3 meter depth. The frame initially having trouble to submerge because the upward force from the bottle is really strong. We try to fill in the bottle with water to decrease the density. After 2 to 3 test, we manage to get the ideal buoyancy for the frame. The test were merely to get better understanding of how object behave in water subjected to the force. Although the movement of water in the bottle make it unstable, at least we get the idea for our next development
