Tedious. Why not simply compare images captured x and 2x units from the camera and show by photoshopping that the smaller image fits 4 times into the larger one? Why not go even further and question the search for a Grand Unified Theory? That is, if the similarity between gravitational and other force laws is merely geometrical, why look for anything deeper?

wow the butter gun was so fake...LOL you put butter on the cardboard and you put butter on the tip of the gun! ya nice try to make a butter gun...at least the physics was ok...=P
That was brilliant. If only someone could give me an explanation for electricity that would clarify it as well as this did for inverse squares, I'd be much more knowledgable.
@RichardRoy2 simple, you have 2 coils. One coil has an AC power source and the other has a load. If you double the distance between the coils then the magnetic field has grown 4 times the size and is 1/4 as strong. Also note that doubling or halving the voltage across a resistive load will have 4 times the difference in wattage because watts = volts x amps. I used to over-voltage the motors on my combat robots for competitions to get silly power at a cost of brief motor life (practical example).
The butter gun example is from a vintage physics video. Anyone know where I can find the original?

Thanks Ringo! You were a crap drummer but by God you know your physics!

What did you do wrong?... you could try using a butter knife instead of a butter gun.
