Putting on the Whole Armor of God 
I have good memories of this being used (by my husband) as the topic for youth firesides many, many times. He would use one of the kids as the "helper." He made "armor" (breastplate, skirt, shin guards) out of cardboard, and put a metal colandar on top of his head as a helmet.
With each addition he would talk about truth, righteousness and faith, gospel, salvation, spirit.....then concluding the talk he would invite the young person to take off the armor.
Instinctively, the person turns to take off the outfit....and my husband had a plastic dart gun (suction cup darts) that he would shoot the person from behind with the "fiery darts of the devil." The ending would be ...never turn your back on Satan.....always defend yourself and never take off your armor of God.
Ephesians 6:11-17
