Original video
Putting a bit in context, this show has nothing to do with magic, it's a dancing contest, so clearly, it's strings... The trick of him being able to float is strings... The thing keeping and moving all the objects, strings too...
If it was something like India Got Talent, judges would be like "can we pass a knife above his head and see him doing it again?" Because we literally never saw anything above his head that could show us there are no strings pulling him in the air.
Calling this magic is fraud
The show is all about dance, the judges were very aware of the strings
