Corrupt Jarate and Bushwaka +Custom Particles

I felt TF2 was lacking... lacking in PURPLE!

Gives the sniper a jar of purple sludge that ,when thrown, spread disgusting corruption to the world of TF2. Oh yeah, it also give him a cool glowy purple blade to match it <3 I plan on adding a cool affect to jarate-d players. But alas, I am to lazy for that

A problem that I can't fix is getting the liquid in the jar to move around, if anybody could help me with this, that would be awesome!
