Why doesn't an ant die when I flick it with my finger?

Flick an ant, or pretty much any other bug for that matter, and it will scurry away virtually unharmed. 

Is there any reasoning behind why it doesn't get blown to smithereens?

Ants in particular are very durable because their exoskeleton is made of an extremely tough naturally occurring substance called chitin (also found in the exoskeletons of crabs and in the beaks of cephalopods).  In addition, ants get their incredible strength from a highly dense muscular structure that also serves to pad their internal organs.
