I found an explanation of Experiment 01 on the Old Superstition Website.
Apparently with a ladder open or placed against a wall it forms a triangle, the symbol for the holy trinity (Christian and the like). Now walking through the triangle would be a violation of the trinity thus putting you in league with the Devil himself... *shiver*.
In my video I went through it forwards thus I am now in league with the Devil. But then I went for a second time around but this time I went through backwards. So I could say that I went arse first through the holy trinity.
Jeez if I don't get hit by a truck soon then I think I can safely say that this superstition is just that... a superstition!
There was another site (Jewel Denson - The Cookie Jar)
that had a very different idea behind it... and I think I agree with her (I assume it's a her).
What she says is that back in the day when people were stupid and were ruled by the church etc. they needed to teach people about safety and so on. Walking under a ladder for example could cause injury... How? Well there's normally someone at the top of the ladder with tools, like a skull crushing hammer or some horrible paint. If you were one of the clumsy types then you'd obviously knock something over killing yourself, the dude on the ladder and anyone else standing idly by. Well not killing everyone but it wouldn't be pretty.
So... In order to stop people from doing this they put the fear of G-d (I type it like that out of respect for my girlfriend) in them by telling them that if they walk under a ladder they are blaspheming the holy trinity. Obviously you'll not get anyone walking under ladders anymore.
Well that leads me to believe that most of the other superstitions out there are a form of control. I'd like to research this theory a little further.
Next Experiment - The black cat.
