Addon: Block Physics
Minecraft's physics are honestly pretty boring, so author made this addon to spice things up a bit. In its current state, you can make explosions look pretty cool, but he also plan on adding more stuff down the line.
This addon adds entities that look just like blocks, which allows author to make some pretty cool stuff, such as explosions which have blocks flying away from them.
