This is an amazing fire prevention gel that can protect a home in a forest fire.  The video is kind of long but shows how information can definitely persuade.

Look at this one and think about how it creates Cognitive Dissonance then look at the next one and see if it does a better job These commercials were actually on the Prudential web site as part of a poll that asked customers which they thought was better.

Notice how the open endedness of commercial impacts your sense of dissonance
Cut the seatbelts The emergency hammer designed to cut seatbelts and break windows.  How often do you really need something like that?  How many people are trapped in a car with a jammed seatbelt and stuck window? 
Break the window with under 12 pounds of force from your keychain.
