Stunt advertising is probably a type that takes outdoor advertising to the next level. This type takes more effort, involves real people, and engenders emotions. One example is from Telenet, a Belgium-based cable and broadband provider. 

In the middle of a quiet street, they placed a button and an arrow that said, “Push to Add Drama.” Once people press it, the quiet town entirely changes into a chaotic scene. Medics, football players, detectives, policemen, brawls, gunfights give people their “daily dose of drama.”

But you have to be careful when taking this approach. First, expect that there will be multiple outcomes. Other people might love your outdoor advertising, while others might view it as a desperate move. Either way, you have to be ready for it.

Also, before you push through with the plan, gather as many insights as you can. Welcome criticisms too, so you can improve your stunt advertising. And lastly, never cause a riot. For example, if you are going to place unlabeled bags in different parts of the city to promote your brand, you might be overdoing it. Before you know it, people will get scared thinking that your bags contain God-knows-what, and they might alarm the authorities. That would be a big flop for your campaign.
