When the fire dancer throws the torch in the air, he is still holding one. When Martin releases the torch in the air, and the dancer catches it, it is the only one he is holding. The other one has disappeared.
Minor detail: Polynesians don't say "Aloha", only Hawaiians do because "Aloha" is a Hawaiian word. If Hawaiians are, indeed, Polynesians, other Polynesians, nevertheless, do not say "Aloha". For example, Tahitians say "Ia Orana" and, in the Cook Islands, it is "Kia Orana". And in Fiji, which is more Melanesian than Polynesian, the word is "Bula". (These words are for the "hello" meaning of Aloha. There are many other words to translate "Aloha" in those other Polynesian tongues.)
