Zener Cards


This is the best tool to use in parapsychology ESP testing. The cards are very well made and will last for years. If you work with the cards for more than 1 hour your hits will go down. Dr. Rhine knew this, I know why. I was doing testing at the lab in Durham in 1982. See if you can find out why.
