For anyone wonder the magic behind that, the spheres have the same refraction index as the water. Another cool trick to fill a jar with vegetable oil, then put some kind of glassware (preferably an unmarked beaker because it is smooth) inside it. The glassware will disappear because the glassware has the same refraction index as the oil.

******* science.
