Have you watched the demo video?
It shows the trick quite clearly.
When it says "The top Sun card is dropped down by the King of Hearts" that is exactly what happens. You have a king on the table, face up, four cards in your hand which have all just been shown to be Sun, then you lay the top sun card face up, and show that the other three cards in your hand have magically turned into kings.
