Reasoning and answer: The remains of the second popsicle melt 2 * 1 = 2 times as fast as the first. The remains of the third popsicle melt 2 * 2 = 4 times as fast as the first. The remains of the fourth popsicle melt 2 * 4 = 8 times as fast as the first. The remains of the fifth popsicle melt 2 * 8 = 16 times as fast as the first. The remains of the sixth popsicle melt 2 * 16 = 32 times as fast as the first popsicle.
The answer: 32
