The liberty gift is made from a dead phish stuffed with cat snit and wrapped in an ammonia-soaked towel.
There are two methods of delivery: Active and Passive
Acftive delivery requires that you fling it or hum it at a target which whould compromise the peace of mind of yopur victim. The active approach usually makes a mess.
The passive approach involves placing or setting the gift on top of your target. The contents of the package tend to seep on to the target and cause corrosive damage.
