Bubbell

The Bubbell is a functional flower added by Botania. When supplied with Mana, it replaces all water in a sphere with a radius of 12 blocks with fake air blocks that keep water from flowing back in, using 4 Mana per tick. The Petite variant of the flower affects a sphere with a radius of 6 blocks instead.

If the flower runs out of Mana or is removed, the fake air blocks will start decaying, turning into regular air, with a 10% chance to turn into water instead.
