🦭 Manatee Lung Volume and Buoyancy: Boyle-Law Trim, the Unstable Neutral Depth and a Seagrass Dive

A manatee controls its buoyancy with lung air that Boyle's law compresses as it dives. Breathe, exhale and use the tail to find the unstable neutral depth, compare the simulated tipping depth with the closed form, and watch the forces on a seagrass dive.
