Which cup will fill up first?
It’s pretty simple but it can get tricky at the same time. Concentrating and organizing the brain and the eyes is critical. Now we’ll see if you can do it, and just have 10 seconds to make it fair.
Several paths are blocked
Now check if you solved it correctly, here is the answer!
It’s NOT cup 1 that will up first, because the path has a blockade at the beginning.
It is also NOT cup 2 that’ll fill up first, because the path has a blockade at the end.
And it’s NOT cup 4 that will up first either, because the path has a blockade in the middle.
Could it be that cup 3 is the only one that can fill up, and therefore, the first one to do it? The answer is yes!
