Tube puzzles are a great way to test your observation skills. At first glance, it looks like all four drinks could be connected to the boy’s straw. However, most of the tubes either cross over each other without connecting or lead to dead ends designed to trick your eyes.

The Challenge

The boy appears to be drinking through a long, tangled tube connected to one of four cups:

• 💧 Water
• 🥛 Milk
• 🍵 Tea
• 🧃 Juice

The goal is to trace the tube from the boy’s mouth all the way to its source without getting fooled by the overlapping loops.

Step 1: Start at the Boy’s Mouth

Instead of looking up from the cups, begin at the straw in the boy’s mouth.

The tube travels to the right, makes a large loop, and then continues downward into the maze.

Step 2: Ignore the Fake Crossings

This is where most people make a mistake.

Several tubes appear to intersect, but they actually pass over or under each other. Since they don’t connect, switching paths at these crossing points leads to the wrong answer.

Always stay on the exact same tube.

Step 3: Follow the Correct Path

If you carefully trace the tube without jumping across intersections, you’ll notice that:

• The path does not end at the Water cup.
• It does not connect to the Milk cup.
• It does not lead to the Tea cup.

Instead, the tube continues around the final loop before reaching the cup on the far right.

✅ Correct Answer: Juice 🧃

The boy is drinking Juice.

Why So Many People Get It Wrong

This puzzle relies on an optical illusion.

Your brain naturally assumes that overlapping tubes are connected, even though they simply cross over each other. Once you mistakenly switch to another tube, you’ll end up choosing Water, Milk, or Tea instead of following the real path.

These visual tricks are exactly what make tube puzzles so fun—they test patience and careful observation rather than speed.

Tips for Solving Tube Puzzles

• Start from one end instead of jumping between paths.
• Treat every crossing with suspicion.
• Trace the line slowly using your finger if needed.
• Never assume two tubes connect unless they clearly merge.

Sometimes the simplest-looking puzzles are the easiest to overthink!

Did you get it right on your first try, or did one of the fake crossings fool you?
