Optical illusions can be frustrating, but it's a great feeling when you finally solve the puzzle.
How you figure them out can also reveal a lot about your brain power, as if you can quickly figure them out - you may be of high intelligence.
The latest head scratcher, courtesy of YouTube, involves a chaotic ship scene and you have to find one very well hidden item among the picture - but that's not all. You also need to find it in seven seconds or less, the Daily Star reports.
Among the ship passengers and stormy sea, it's a toothbrush that you need to find and while it sounds easy enough - it's actually quite challenging. There are many hidden items within the busy animation, therefore challenging patience and attention to detail.
Those with sharp focus should be able to locate it in the quick time frame - so are you up for it?
The toothbrush is blending in with its surroundings, making it so difficult for anyone to find it at first glance. But attention to detail is required to find the object in the picture.
Need a hint? Try looking around the left side of the image.
If you're still struggling, scroll further for the answer - but consider this a spoiler warning.
You'll find it hidden in the borders of the ship located next to the man with dark brown shorts.
If you're looking to further challenge your focus, why not try to spot the hidden error among the flock of chickens. Another tricky brain teaser challenges you to find the odd letter in a sequence of Ms in just 11 seconds.
Or, if you're looking for something different, one optical illusion can point out your least attractive personality trait.
