UnderCurrent tips its hat to Betta Home Living for a very unique competition to promote its refrigerator range. Taking the ‘jelly beans in a jar’ concept to a massive scale, the retailer is challenging its customers to guess the number of bouncy balls it has stacked inside a fridge to win the fridge itself.

To give customers help in guessing, Betta has lugged the fridge up to a high roof top and shot a video of the fridge opening and causing a minor littering hazard on the street below.

Take a look and make a guess. If for no other reason than to give a bit of credit to the poor interns (we presume) who had to hike the fridge up onto the rooftop.

Head to the Betta website before the end of the month for details on the competition and the full entry form.
