Chewing operated drill and a teeth lathe! The brilliant Mouth Factory by Cheng Guo

Up until now the mouth has merely been a cavity into which one places cake and, occasionally, mutter a sonnet. Finally, we can put it to good use with the various instruments from Cheng Guo’s Mouth Factory.

These elegantly engineered tools will leave your hands free to make a sandwich or write a letter or even play the piano, thus serenading your weekend DIY antics. The graduate of design products at the Royal College of Arts lists his tools as “chewing drill, teeth lathe, tongue extruder, mouth breath rotational moulding and vacuum form machines” – all functional celebrations of your mouth’s potential.

Harnessing the “capabilities and versatility of this wondrous organ and correlating facial expressions, re-contextualised within the realm of production”, this is one bodily enhancement that won’t make it onto The Only Way is Essex but will turn you a very fine door handle for your home.
