PICRIC ACID 
Picric Acid is an organic compound that is highly unstable and sensitive to shock, heat or friction when dried.  
 
If the bottle that the chemical is being stored in is old and the acid inside has dried, some crystals may have formed on the threads of the bottle and the friction created from removing the cap might be enough to detonate the container.
