A trick introduced in 2010 is a modern version of the bag escape, replacing the traditional sack with a black trash bag apparently filled with helium. Teller is placed in the bag which is then pumped full of helium and sealed by an audience member. For the escape, the audience is blinded by a bright light for a second and when they are able to see again, Teller has escaped from the bag and Penn is holding it, still full of helium, above his head, before releasing it to float to the ceiling. The duo had hoped to put the trick in their mini-tour in London; however, it was first shown to the public in their Las Vegas show on August 18, 2010. In June 2011, Penn & Teller performed this trick for the first time in the United Kingdom on their ITV show "".
