To push through goo, use itty, bitty propellers :




A really nice example of bioinspired engineering, By stealing a trick from bacteria, tiny human-made vehicles can cruise through goo.
Researchers in Germany have designed metal and glass micropropellers that travel through mucus in part by liquefying their thick surroundings. The propellers mimic the activity of ulcer-causing bacteria, and could help inform the design of microbots or drug delivery systems.
