Projectile containing chemiluminescent compounds for marking a target

Abstract

A projectile is made of a first (inner) body having a liquid tight interior cavity that contains a volume of a first liquid, and a second (outer) body that contains the first body and a volume of a second liquid. The second body also has a liquid tight interior cavity. The first and second liquids, when mixed, can start a chemiluminescent reaction. The second body is adapted to not rupture when the projectile has been shot at a target and to only rupture when the projectile has impacted the target.

What is claimed is:  
     
         1 . A projectile comprising: 
 a first body having a liquid-tight interior cavity that contains a first volume of a first liquid, the first liquid being one that when mixed with a second liquid starts a chemiluminescent reaction; and    a second body having a liquid-tight interior cavity that contains (1) a second volume of the second liquid, and (2) the first body, the second body having a round exterior surface, the second body being adapted to not rupture when the projectile has been shot at a target and to rupture when the projectile has impacted the target.    
     
     
         2 . The projectile of  claim 1  wherein the first and second liquids are an oxalate and an activator.  
     
     
         3 . The projectile of  claim 2  wherein the first liquid is the activator and the second liquid is the oxalate.  
     
     
         4 . The projectile of  claim 2  wherein the first body is made of gelatin.  
     
     
         5 . The projectile of  claim 2  wherein the second body is made of gelatin.  
     
     
         6 . The projectile of  claim 1  wherein the interior cavity of the second body is round.  
     
     
         7 . The projectile of  claim 6  wherein the first body has a width that is no greater than approximately one-half an interior diameter of the second body and no less than approximately 30% of the interior diameter.  
     
     
         8 . The projectile of  claim 2  wherein the oxalate further includes a color material to mark with color an impact spot on the target.
