] Metallic rods about 500 times smaller than the width of a
] human hair have been turned into tiny "propellers" by a
] Canadian research team.

] Their motion is driven by addition of hydrogen peroxide (H2O2) to
] the solution in which they are contained.

] A reaction at the free ends liberates gas bubbles to provide
] thrust, turning the rods at a near constant speed.

] Only when the supply of hydrogen peroxide fuel is exhausted do the
] rods stop spinning.

There is a redundant post from bmitchell not displayed in this view.
