This experiment always reminds me of Beakman's World because that's where I first learned of this. :-)
Never again watched it but that was a big science jump for me.
The thing is, i was a science kid from the start and discoverh and national geographic was amazing.
I remember watching a show "is.it real?" When i was like 7-10, not sure but one episode was about stigmata. Just random.thing i remember.
Then many years later, constantine movie i was watching on tv and i recognized the hand and said "thats stigmata".
Stuff like that happens with me daily. I like.it
