While there's no official record documented, a sped up video owned by someone using the YouTube name "hmammy", shows how a giant Jawbreaker slowly dimishes its size.
The owner claimed that it only took him 3 hours while driving down boring highways on a road trip.
According to Guinness, the largest jawbreaker weighed 12.6 kg (27.8 lb) and was made by Nick Calderaro, an employee of Oak Leaf Confections Co. at their headquarters in Scarborough, Ontario, Canada on 29 May 2003.
The jawbreaker measured 94.6 cm (37.25 in) in circumference and took 476 hours to make between 7 January and 29 May 2003.
