This creative billboard advertising stunt for Le Festival de Magie de Québec shows a taste of the kind of magic that you can expect from attending the festival.
The billboard set up to look as though a guy was putting up the billboard pasting where people could easily see him, which doesn't seem too out of the ordinary. However, in a few moments, the red broom in the guy's hand starts to magically lift and float away, seemingly under the control of the guy.
Although most of the public probably never found out how this magical advertising stunt was pulled off, it simply involved a mechanical system behind the poster. Either way, the illusion was pretty entertaining and it would certainly make you do a double take if you weren't expecting it.
