I amended the previous post having neglected to stipulate the unequal U leg length yesterday. in such a way that the much longer thin side must not be so long it does not start spilling the buoyant spheres onto the slant across which they ferry glide float roll to and down the fat one again .. ad infinitum

Note the syncreelisticallee personified prefigurement in duos, couples and combos like Laurel and Hardy
