umm i dont think he used melting point to perform the coin thru glass. i think it was either passin thru or some kind of a more uncommon trick sold in the market, or maybe it is his own personalised trick. i would not reveal too much about melting point as it wouldnt be nice

but judging from all his actions before he even started the trick, its almost 100% impossible he was using melting point o.O as for the saltshaker trick, im speechless about it; it was beautifully performed
