As you have seen in this lab, the density of water is near 1 g/cm3. Anything with a density lower than this will float in water, and anything with a higher density will sink. Imagine you are building a submarine. How could you be sure to have it sink and then rise? Make sure its density is always above 1.0 g/cm3. Make sure its density is always below 1.0 g/cm3. Develop a way to adjust its density so that it can be above and below 1.0 g/c
