New brain teaser challenges users to identify which glass fills first from a tap

A new brain teaser is gaining attention on social media, asking which glass fills first from a tap. The puzzle features seven glasses connected by tubes at different heights, with water flowing from a tap above. Users have debated the answer, with some claiming glass 3 fills first, while others argue for glass 4. Comments suggest that glass 4's pipe is closed, preventing it from filling, while glass 1 must fill glass 3 first. Another puzzle circulating online involves a series of math equations that challenge users to find a pattern. The equations suggest a different arithmetic operation is needed to solve for the final equation.
