Plastic hollow submarine model measuring 18.5 cm in length and 5 cm in diameter. Included in the set is a transparent tubing and syringe to pump-in and remove air from the submarine accordingly.
When air is removed from the submarine, water will rush in making it heavier and it will start to submerge. When air is pumped back in, the water will be forced out making it lighter and it will surface and float.
