Convection Current - GCSE Physics Practical.
This is the start.www.youtube.com/watch?v=Ph4Re3CrUmY
Have two spare 787 motors from a barnyard find. One my son shall rebuild & the other I'm going to use for numerous crazy arse experiments in RV lubrications, yes sir.
Got to construct a practical, working lab bench + a half dozen other items. Will video when I get all the ducks lined up.
Try to get it done by late April, or not.
