If you calculate the total linear momentum of the system, including the floor (and earth), it'll be zero. Same for angular momentum.

High precision equipment won't help because you haven't made a quantified, testable hypothesis (that I know of). If you do it in an evacuated room with frictionless parts and high speed cameras, and the results are consistent with computer simulations, then what will that tell you? Maybe the effect you hope for is too small to detect with that equipment. So it's a probably-pointless experiment.
