Bubble - asdru22/Cognition GitHub Wiki
Slime Bubbles are produced when Greek Fire is placed below a slime block. Honey Bubbles are produced when Greek Fire is placed below a honey block. This happens every 10 seconds. If there is a block above the slime/honey the bubble won't form until the block is broken/moved.
Almost every entity can enter a bubble, including players and items. Bubbles pop when shot at or after 10 seconds. Bubbles can be moved horizontally by Gusters. Players can dismount bubbles by pressing the sneak button repeatedly.
