Zahramay Falls is the home to Shimmer & Shine along with other genies & sorceress. Although normal humans are not allowed to visit Zahramay Falls, Leah & Zac were given exception by wearing genie outfits to blend in. When they are ready to leave to go back to their human world and come back to Zahramay Falls also, Shimmer and Shine call Leah and Kaz calls Zac in a special chant if they need them, they would rub the Leah's bottle and Zac's lamp, the magic will carry them, get inside then the bottle and the lamp go poof. While Leah and Zac through the portal, the magic will change back to the normal clothes when they go back home and change back to the genie outfits when they go back to Zahramay Falls. However, this is only a prediction since we never saw this on camera. The camera goes inside of the bottle from the start of the opening scene in Season 2 except on Season 1.
