Minecraft: Enderman separation and DEATH BY MINECART!11!1ONE!!

Here I show enderman separation based on mob health inspired by red3yz and further tested by Roboticaust but then I use a killing option I've never actually seen used by any of the many minecrafters I watch here on youtube.

If I use this in my world I will have to tinker around with the kill spot but the downside of this kill method is loot collection is messy. When a mob or player dies loot sort of explodes out from that block and can be unpredictable so at the point where the cart leaves the track loot often kicks back onto the block behind it.
