I hope this is the right section to ask this.

Is there any existing effects/gimmicks that can let a magician cause a can to crush by itself?
Actually, specifically, the can crushes itself just sitting on the table without the magician touching it.
But if there's any variations of a somewhat smiliar effect that anyone knows of, I would be most grateful for the information too.

If there's an existing effect, can please advice on the inventor, effect name, and source where it's published and/or which dealer it's currently available from?

Cheers

Perhaps I should explain myself.

I think I may have come up with a method to the above mentioned effect.
Did I really come up with something new? Or is this like the dozen other time where my ignorance is giving me much bliss?

From the lack of replies, am I right to assume that nobody can remember anything the achieve this effect?

My method was published back in MUM in or around 1985, I doubt I even have a copy of it anymoer but if youw ant to chat about PM me.

I remember the method from the MUM! That was a teriffic idea. I used it for a few years in my comedy club act in the late 1980s.

I'm certain I have a copy of that issue filed away someplace.

I came up with my own rather straight forward version of this, slightly different from what's mentioned in the original post though as the can self crushed as it was resting in/on my hand. I used it for years until a cleaner in a hotel I was working at threw it away thinking it was an ordinary can .... and never got around to making up another one.

Today's soda cans are so thin, you could pull them flat with just a string inside.

I'm not sure if this is the same idea as yours, but I just recently saw an ad for a soon-to-be-released trick (DVD) called "Emptied," by Paul Kostrach, to be marketed by Black's Magic.
