>>12497841say you create an entanlged pair. one is spin up and one is down.
say you measure the spin 1 with an off kilter polarisation filter and spin 2 with a truly aligned filter.
there is a chance that the misalignment of the filter will tip the spin 1 into up 2/3 times and down 1/3 times
the filter at 2 will not tip the spin and will measure faithfully either up or down 1/2 and 1/2 respectively.
basically the point is that every time you measure at 1 first you will notice that the measurement at 2 has changed from a faithful 50/50 to now 2/3 being down and 1/3 being up, representing a reflection of the influence the misaligned filter has had on the first particle. this shouldn't happen if there wasn't spooky action at a distance.
