It seems that we aren’t running out of new edible inventions, as scientists have built an entire edible robot. Researchers from Johannes Kepler University in Australia built a robotic elephant trunk from an edible and biodegradable gel. The edible robot is a step forward for building child-friendly toys, as Futurism details:
The robot is largely made of gelatin. In addition, it contains citric acid to stop bacteria from eating it, and glycerol to keep the whole thing soft and hydrated. The material itself didn’t dry out for over a year, and the elephant trunk was able to bend and straighten over 330,000 times before cracking, according to research published Monday in the journal Nature Materials.
