How do Dragon Clan members know how to make dragon balls?

[SSJ2]

I recall Kami saying that it was almost instinct? Can someone correct me there if I am wrong. But do the real Nameks practice making them, or just make them when necessary?

Maybe it's an instict but it can also be practiced.

Kami said it was an inborn instinct, and that his ancestors had passed down the knowledge to him or something like that. The ability can probably be trained though, since Dende's dragon was more powerful than Kami's and Moori powered up the reviving abilities of Porunga.
