If it works the same on a smooth bottom boat with no fins, then it might have potential as a means of propulsion in outer space. Changing and controlling inertia of a space craft via internal gyro dynamics.
You could just place the whole apparatus in a large bowl or pan and float it on water.
Yup. Gyros move like magic! I'm interested in the implications of such movement... which I am confident has to do with interactions with the "ether" and with possibilities of free energy. See my other gyro experiments here: https://mes.fm/experiments-playlist
