This is a head wreck.
A magic trick that can "guess" your age and shoe-size has resurfaced and divided the internet this week.
While some say their minds are blown, others are not that impressed at all by the six step equation.
The trick involves asking someone to write down their shoe size without telling you.
They must then multiply the figure by 5, add 50, multiply that number by 20, add 1015, and subtract the year of their birth.
They should be left with a figure that includes their shoe size and age, making up a three or four digit number.
Although it's been around for a while, it is probably doing the rounds now because January is the best time to do the trick.
This is down to the fact that once your birthday has passed, the numbers are out, so the earlier in the year the better.
While many people are getting great craic out of it, others are far too cool.
