Explosions in Minecraft are much more powerful and interesting than in real life. The main difference is that there is no limit to how much energy you can throw into the air, and the energy that you put out will be instantly converted to various forms of energy, including heat, sound, light, and even matter. If you want to have more fun and be able to throw a bigger bomb, you can change the texture pack for a nuclear bomb and create an explosion with TNT or dynamite. If you are interested in explosions in Minecraft, you can download this mod for TNT and dynamite.
