Joybond has developed and implemented an intricate device that can not only cool but also heat (although it is not very clear why) watermelons. And also serves the purpose of convenient transportation to the place of eating. The wonder-cooler holds 14 liters, has a size of 50.2 × 35.4 × 39.2 cm and weighs 6.3 kg.
The device costs about $ 230, but is available so far only in Japan.
