When used as a weapon, the Bomb deals 5 full hearts (20 hitpoints) of damage to any mob or player that is standing in point-blank range. Furthermore, it will release smoke particles, and has a knockback effect of 1-2 blocks.
When used as a tool, the Bomb can destroy Cracked Cobblestone and Cracked Stone, at a range of up to 3 blocks, depending on the position it lands when thrown.

After 4 seconds, the Bomb explodes, taking a portion of the Cracked Stone and Cracked Cobblestone with it
There is a trick called "bomb jumping", which sacrifices a player's health in exchange for covering a massive distance. The damage taken can be reduced when using the umbrella, to reduce fall damage.
