Is it possible to drop a redstone torch so it powers something?

On the black plasma animation "Survival" a character sets up a redstone trap. In one of the sequences, a dropper (or dispenser, couldn't tell) is activated and drops a restone torch. this torch falls nearby a powered rail and activates it. Is this actually possible to do in game?

I don't believe this is possible in-game. An item dropped in that manner would drop as an item and would not power the rail. This was an effect added by (the quite skilled in my opinion) animators. It could however drop onto a wooden pressure plate if you were trying to achieve the same effect.
