After four months of work, scientists have found the perfect way to hold a burger. The ideal method is to have thumbs and little fingers supporting the bottom bun and middle fingers spread evenly over the top. The Japanese mechanics and engineers said this produces a 'firm grip that won't crush the toppings'. But not everyone agreed with this method. YouTube user Forfluf had a different suggestion, and wrote: 'Eat from the wrapper, no mess on your hands, keeps the burger intact, prevents spillage, keeps grimy hands from touching the food. 'But don't listen to me, I'm no scientist.'
