Cucumbers?!

I don't know it this is true but I saw a video yesterday. Slice a cucumber long ways and scoop out the seeds. Place the seeds in water and stir. The ones that fall to the bottom of the glass are good seeds. Take them and lay them on a wet paper towel, sprinkle with cinnamon (supposed to speed up the germination). wrap in the paper towel and place in a zip lock bag. Sprouts should start growing in 3-5 days.
Transfer to pot and presto!
