This Robot Crawls Through Acid, Ice and Fire: Is Squishy

This robot, developed at Professor George M. Whitesides’ lab at Harvard University has recently become untethered, so it is off the leash. This creepy crawler is super tough and can function in subzero temperatures, 40 km/h winds, puddles of up to 5 centimeters of water, and 3,000 Kelvin methane flames for up to 50 seconds.
