Video Summary

In this problem, identical balls are placed in five identical test tubes, and water levels are analyzed after adding water. Test tubes 1, 2, and 3 have equal water levels, despite different numbers of balls. Similarly, test tubes 4 and 5 share a water level, which is twice that of 1, 2, and 3. When balls are removed, test tube 3, with an equal water height despite more balls, has less water compared to 1 and 2. While test tubes 4 and 5, with the same logic applied, determine test tube 5 has less water than 4. Among 3 and 5, test tube 3 remains with the least water. So, the answer is test tube 3.
