Engineers at MIT have built a compact machine that flaps its wings to travel through air and water with equal capability. The device tips the scales at 250 grams and reaches flight speeds near 6 meters per second while managing almost 1 meter per second when submerged. It also exits the water by angling its body and pushing straight into the air without any paddling or extra propulsion.

Their houses do not fight the flames or winds at ground level, they simply move out of the way.
