Natural coals always needs a stove burner in order to light. When it says its easy to burn, it really means they light FASTER on a stove burner compared to other coals I guess.
Just buy a coil stove burner from walgreens or amazon.

Since your folks arent cool with the hookah, just light them in your room :P. put a fan near an open window and light the coals right next to them
Haha like me!
