Just watched it. As with any other magics, it looks impossible and amazing. But again as with other magics, there's got to be a way
The fact he used a walkie-talkie is cunning. While he could just shouted inside the bin; the walkie-talkie definitely helps him to hide the fact that he might be getting off the bin while remaining contact with communication.
This must be true given the fact that he must had escaped from the bin while talking for the trick to work.
Identical twins is definitely there, given the time constraint of the whole performance.
His twin must have been waiting at the rooftop for a while.
now the riddle comes down to how he escaped from the bin.
Here's my thought:
The bin bag inside the bin might reveal something
Several pedestrains are involved. If the bin is originally heavy, many man help turning the bin over might hide the weight effect of the magician. Hd might be hidding under the bin bag with yoga. You never knows. It's possible
I can't be sure.
He might even had escaped through underground as well.
