Batteries Caught, Extruded

MIT says that every year in the US there are more than 3,500 reports of swallowed batteries. If left in the stomach or esophagus these can burn the tissue. They have designed a new indigestible origami meat robot could be deployed in these scenarios to find the battery, pulling it free from the tissue and guiding it toward the colon for evacuation. Jeff and Anthony discuss the idea of robots wrapped in meat, and compare stories of swallowing the wrong things.
