Minecraft Experiments - The Large Mob Collider

This is a collider I built to study the effects of smashing different creatures together at high speed after studying the results from spoonmonkeyuk's test with chickens. In this video I test out Pigs and Creepers.

Here's the save file if you want to try it out for yourself, just make sure you give me credit for it you use it in a video:

You will need WinRar to unzip the file and either the Mob Spawner Gui mod or the Single Player Commands mod to spawn the creatures to use in the collider.

The save file also includes my hatch bridge and mini Gatling gun, and a very long minecart ride to a tnt canon as they were made in the same save file.
