Well, obviously not by magic! This is simple science. The two liquids have different densities from each other. Basically, the lighter liquid will float while the heavier liquid will sink. You would see the same result if you had removed the card entirely, except this way is prettier and looks more magical.
Hope it clear your doubts. Appreciate your remark and participation. Thank you very much. Want to view some fun and interesting stuff, feel free to join us here at 笑笑小電影. Enjoy viewing, and have a good day.
