The Gravity Core Block is a redstone-powered device that creates an 8-block radius anti-gravity field, causing all mobs and items within range to fall upward instead of down. Simply place the block and power it with a redstone signal to activate the gravity-flipping effect, or remove the redstone power to turn it off. Creative mode players are immune to the effect, and entities affected by the upward gravity won't take fall damage.
