Free floating crystolecule
Getting crystolecules into huge scale free space should afford some easily manageable conscious effort.
If charged they than can be manipulated with conventional techniques, electric fields, magnetic fields, and optical traps.
Cooling them down aka slowing then down is possible so far that gravity acting on them can be observed.
But these crystolecules are far outside machine phase deep inside gas phase (or dystactic phase).
Instead getting crystolecules down to low speed and
keeping them close to the emitting source in a small volume and
having them without a charge is likely very difficult.
Due to intercrystolecular forces being many orders of magnitude bigger than gravity
either they stick like hell or they fly off like hell. There's no falling off by gravity.
