What is sweaty dynamite?

It's considered pretty dangerous. It's when, due to age, nitroglycerine begins to seep or 'weep' from inside the sticks of explosives, making them look "sweaty" on the outside.

Earlier this week, Benton County Deputies responded to a call from a Richland resident (didn't say location of yard) who came across an old can of explosives buried in their yard. The homeowner was doing some excavating for construction. Authorities didn't say what day this week it was reported. The can was marked 'dynamite' and contained several sticks.

Deputies said the dynamite was "sweating" so they called the Richland Bomb Squad. This video captures the detonation. Pretty large! Imagine if the homeowner had not taken precautions!
