THIS is the brainteaser that challenges you to become nosy and spot the time traveller at the 1950s park.
Everyone can see the group of people chatting, but only those with razor-sharp vision and spot the person who does not belong there in seven seconds.
This puzzle will remind you of the last time you were hanging out at a park with your pals, and you spotted someone looking suspiciously futuristic.
Upon closer inspection, you see that the person isn't a person, but a super high-tech AI hologram projecting in from who knows when.
The longer you look at it, the easier it becomes to notice the constant glitching and bizarre pauses in conversation.
You thought maybe it was just them not enjoying the conversation, but then you remember you are an absolute delight to be around, so that isn't a reasonable explanation.

After that, a time traveller is the next logical step.
This teaser is tricky because you don't have much context for what you should be looking out for.
The fact that some of them are partially hidden behind others doesn't help either.
The key to this teaser is to pay attention to any technology you recognise today because remember this is set in the 1950s.
Are you ready, because the clock is ticking!
If you're struggling, a hint would be to focus on what people have around their necks.
People who are able to solve the puzzle quickly possess good observational skills and high cognitive speed.
It tests your ability to process a high volume of visual information and the ability to concentrate under high amounts of pressure.
How can optical illusions and brainteasers help me?

Psychologists at The University of Glasgow found that staring at an optical illusion can improve eye sight by allowing you to see small print.
Escape London says puzzles can also give your mind a great workout and may "boost your brain's activity" which "reduces the risk of dementia."
These can help to stimulate several parts of the brain at the same time.
