Get your work collegue/family member to wear the tin hat and stand them 6 feet away from the computer screen and play the video on this UK Government BBC website.

http://www.bbc.co.uk/bbcthree/videohub/esptest.shtml

Just remember the following;

The play button actually has 5 links

Circle - Top Left
Cross - Top Right
Wavy Line - Bottom Left
Square - Bottom Right
Star - Centre

Enjoy...LOL..(BTW a before test, where the victim gets very few psychic thought transmissions correct then rerunning the the test with the tin hat, where the victim gets them all correct is even more entertaning )
