Bubble Column

Bubble column is a block generated by Magma Blocks and Soul Sand, other blocks in water. Like air, it cannot be mined.

Properties

 * The player can replenish their air supply.
 * When moved by piston steady water is generated.

Vortex

 * The vortex can be determined by downwards wandering air bubbles.
 * A vortex draws entities downwards.
 * When riding a boat over a vortex the boat starts to shake and is finally sunk when staying over the vortex.

Lift

 * The lift can be seen on vertically rising air bubbles when using soul sand.
 * A lift draws entities upwards. The longer an object is rising through the bubble column the faster they will go. When the force is high enough, the object will shoot out of the water.
 * When jumping on a lift, the player will be repelled about one block upwards.

Obtaining
Bubble columns cannot be obtained, but set by commands for.

Natural generation
When generating the world, ravines and underwater ruins will be created below the water surface. When having lava there, some lava will be converted to obsidian, some to magma blocks which will generated bubble columns.. When placing soul sand under water, lifting bubble columns will be created..
