The facts on the card
The card carries these facts from its Wikipedia article.
- The pressure of a fluid increases with depth below the fluid's surface because of the weight of the fluid above.
- Thus, the pressure at the bottom of a container of fluid is greater than at the top of the container.
- Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Buoyancy article was read about 140,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 69 and blocks with 44: each hit it takes is cut by 18 %.
