Let the whole office join in on this tea break teaser as you serve your hot drinks in this heat reactive mug based on the classic British newspaper game ‘Spot the Ball’. Pour your hot drink into the mug and watch as the spots melt away to reveal to true location of the ball. We appreciate that pretty much the entire planet, with the exception of the UK, seems to have escaped the Spot the Ball competition so for the rest of the world, here is a brief explanation: Spot The Ball was a popular newspaper game where the player had to guess the position of a ball that was removed from a sports photograph. The game was very common back in the 70s and 80s, and players would pay for each attempt at guessing where the ball actually was. So whether you were a natural at guessing Spot the Ball in British newspapers back in the day, or are a member of the other 6.8 billion people on earth that are generally bemused by the strange gambling habits of British people, we’re sure this mug will cause a stir in the office. So next time you make your morning cuppa, ask your friends to guess the correct position of the ball and then add hot water to reveal the correct answer. Are your friends willing to risk it for a biscuit?
