Polish students have invented what could be the world's very first vending machine for that most beloved post-pub treat, the doner kebab.
Students at the Warsaw University of Technology have been crowding excitedly around the new machine since a team from the Faculty of Automotive and Machinery Engineering revealed their invention. They spent two years working on the innovative project, which Radio Eska in Poland claimed was definitely the first in the country and probably the first in the entire world.


The Kebs & GO project works by having kebabs prepared twice a day at a restaurant, before they are stored and refrigerated in the vending machine. When someone orders a kebab, which costs 10 zł (£2.11), it is heated up and dispensed four minutes later.
Two types of kebab meat, beef and chicken, are currently sold in the machine, along with mild and spicy sauces. According to Eska, the inventors have promised that a vegan or vegetarian kebab option could be coming soon.
Although a kebab vending machine has not been invented before, there have been other weird and wonderful versions of the snack dispensers.
In 2012, a caviar vending machine, which gives customers 28g (an ounce) of the fanciest Imperial River Beluga caviar for $500 (£375.77), was launched at malls across LA. There are cheaper options though, as the machine will also dispense American Black Caviar for $30. The creators had to get temperature, oxygen, moisture, ventilation and lighting levels to work perfectly. It is also possibly the vending machine with the tightest security in the world, including no less than three cameras, due to the pricey contents.

The Australians invented a hot chip vending machine which take about two minutes to cook. Peter Malone, the CEO of the Hot Chips Company, told Radio 6PR in 2016 that there is no risk of the machine setting alight because it uses brown rice oil, the "safest" possible, and crucial electronic processes turn themselves off if it is knocked over.
