A riddle is a statement, question or phrase that has a double or concealed meaning, put forth as a puzzle to be solved.
One riddle leaving Britons scratching their heads is claiming to only be solved by “smart people”.
The online riddle featured on SilverDoorApartments.com comes with the intro: “Think you’re the smartest one in the office?
“Our collection of head-scratching riddles and brain teasers will settle the battle once and for all…”
It asks for people to identify what killed a man.
The riddle goes like this: “Two men had lunch together and ordered iced teas to drink.
“One man had five during lunch while the other man only had one.
“All of the drinks were poisoned.
“The man that only had one drink died, but the man that had five drinks survived.
“How can that be?”
The brain teaser will leave you scratching your head looking for the answer.
However, there is one simple answer to this riddle.
The man died as the poison was in the ice and the man who drank five iced teas never let his ice melt.
The man who drank one iced tea and died, nursed it over the lunch, letting all his ice dilute.
A tricky one, with the creators claiming this as one of the brain-teasers only smart people can solve.
Another brain teaser leaving the internet baffled is an optical illusion, presenting viewers with a four-part grid.
The image asks of the viewer to identify how many separate colours are used in the makeup of the grid.
Using light, colour and patterns, many optical illusions trick the brain into seeing things that aren’t really there, or seeing a distorted version of an image.
They occur because of the brain trying to make sense of the image and constant goings on around us.
A good optical illusion can leave you dazed and confused, scratching your head for the correct answer, while your brain teases you.
