In-World Buoyancy

Think before you swim!

This mod adds realistic buoyancy physics for items in Minecraft. When you're in water, items from your inventory start to float and drop out. Liquid containers like buckets automatically empty themselves and refill with water. Some items transform under moisture exposure - for example, books get soggy and turn back into paper.

An experimental feature is also available: liquid sources can only be removed using appropriate containers. All listed aspects can be configured and combined according to your preferences.
