| Abstract: | The demonstration was carried out upon a kind of liquid suiface tension phenomenon respectively from three methods such as theory,disproof and practical calculation. The results indicate that the resistance which people perceived when they transfer objects with flat underside slowly from water surface was not due to atmospheric pressure but from liquid surface tension. |

| Keywords: | atmospheric pressure underside flat liquid surface tension |
