Now, what do you see?  Do you know why ?
Karena ringan, gas karbondioksida yang terbentuk akibat pencampuran soda kue dan asam sitrat bergerak ke atas sambil membawa air. Gerakan gas dan air ini mirip lava yang sedang mendidih. Karena lebih berat dari minyak, air yang terbawa oleh gas ke atas kembali ke bawah.
