✦ Synopsis

We have developed a new algorithm for the calculation of surface tension and contact angle. This method is applied to the motion of water striders. Two types of movement are found in the experiment and these are analyzed by the simulation. The comparison of these results show that there are two distinct propulsion mechanisms. In the conventional breaststroke type, the leg speed must be larger than phase speed of surface wave which is called DennyΓ•s paradox. In a new butterfly type, even the infant water strider can swim and the DennyΓ•s paradox is resolved.

The surface tension of water has been measured in quartz capillaries with radii from 200 down to 40 nm. It appears that the surface tension does not differ from the known (bulk) values in the temperature range from 8 to 70 β€’ C, within 1% experimental error. The dynamic contact angle, ΞΈ d , vanishes
