Normal lung tissue floats because of all the aveoli (tiny air pockets).
Lung tissue would typically sink in water because it is denser than water. The air sacs in the lung would collapse and the tissue would be more solid, leading to sinking rather than floating.
Your lung is totally elastic organ. If air enters the pleura, lung will contract. It will be useless for respiration in such case. You have to put under water seal to take out the air from the pleura. If air happens to enter in both of the pleura, you will die in 5 minutes.
Nothing noteworthy happens if mentos are put in tap water; they simply dissolve slowly.
