Engineer Syringe Jump

Engineers can super jump with the help of one or more medics by exploiting a physics bug in TF2.

1) Engineer builds Dispenser
2) Engineer jumps on top of dispenser
3) Medic(s) crowd around dispenser
4) Engineer jumps as fast as possible
5) Medic(s) shoot syringes at engineer

If the medics can keep a steady stream of syringes hitting the engineer he can get very big boost in the air. You can use multiple medics to get higher in the air.

John M sent me this exploit and it works really well on cp_skyscraper.
