    Thanks AH. Found the right word. "Antithixoropy-shearing can
    promote temporary aggregation rather than breakdown, due to the collision of these attractive particles --this results in anti-thixotropy."

    This non Newtonian fluid could be useful to replace the fluid in automatic transmission, or if the response is fast enough, body armor.

    What if I load the lake with flour, that would give the stone more bounce.:cool:

    Or as Frosty like it, more bounce for his cannonballs and bombs.:p

    Listen --its frogs that see the stone coming then head it on the the next frog.

    My Dad told me --seems logical.

    Thats why if you try it with a brick it just splashes and sinks --the frog isnt strong enough.

    I think it's gravity and atmospheric pressure that let's the stone skip the pond

    If Stone is wanted by the Bobbies, he might skip across the Pond in an effort to evade.

    If the Bobbie wants to get stoned he/she doesn't need to skip the country.

    A little more challenging is to skip the pond across stones-
