One thief smiled and said, "There is no hurry; you have to tell us one thing truthfully."
Magician Jack "Yes, ask."
Thief: "What type of water is in these bottles," pointing at the black bag filled with four bottles!!?
Sarma: "We are telling you the truth; there is only water in these bottles."
Thief: "Okay, let me confirm," looking at the other thief with a smile and holding one bottle in his hand, opened the bottle, smelled it, and said to the second thief, "It looks like water," and then he emptied all the water onto the floor.
Magician Jack, looking at him, asked, "Now, do you believe it is water? Leave the other bottles and go from our room."
The thief, smiling and holding the second bottle, did the same, emptying it. "Yes, this bottle also has water," he said, looking at the magician.
Magician Jack: "Don't waste our water; we have to take this from here to our hometown as a gift river water."
