Specification
Brand : FYYKXWD
BulletPoint1 : *This demonstrator can vividly demonstrate the ups and downs of submarines and help students deeply understand the practical application of Archimedes' law.
BulletPoint2 : *This instrument uses a hollow transparent sphere as the air chamber of the submarine, which can intuitively demonstrate the drainage and exhaust conditions of the submarine, and can enable students to grasp when the buoyancy (the weight of the object discharging liquid) is greater than the weight of the object, the object floats; when the buoyancy is less than the weight of the object , The object sinks.
BulletPoint3 : *The submarine floating and sinking demonstrator is composed of a transparent spherical air chamber, with suction and exhaust holes at the top, and water inlet and drainage holes at the bottom. The accessories are transparent plastic tube and suction and exhaust tube.
BulletPoint4 : *Do not collide or drop the diving ball gas chamber and the transparent water tank to avoid rupture, and prevent with corrosive agents and gas to prevent aging and cracking.
BulletPoint5 : *Drain the water in the air chamber after use, and keep it for later use after drying.

Instructions
1. Bring your own transparent water tank or beaker (about 10cm in diameter and 15cm in height) to pour 3/4 volume of clean water into the transparent water tank.
2. Push and pull the piston several times in the water in the suction and exhaust cylinder to make the piston and cylinder wall lubricate and seal, and push the piston to 10 ml near the top.
3. Weigh the submarine's own weight with a strip box dynamometer and make a record.
4. Connect the suction and exhaust tube with the suction and exhaust holes of the submarine's air chamber with a transparent plastic tube, and then gently put the submarine into the water. At this time, the submarine floats on the water.
5. Slowly pull the piston of the suction and exhaust cylinder outwards, the air chamber of the submarine is exhausted, and the water is sucked in from the water inlet at the bottom. At this time, the submarine sinks slowly as its weight increases.
6. Weigh the submarine with a dynamometer and record the weight of the sphere.
7. Push the piston inward again, the air chamber inhales, the drain hole drains, the weight of the submarine gradually decreases and floats slowly, and then the weight of the diving ball is weighed with a dynamometer, which is just the weight of the ball itself.
