Y'know, Uday has just been flooding the market with cheap pocket magic lately......but, whatever sells......that's what people will buy!!
This is an old trick......I had one when I was a kid. The "coin" could stand to be about 1 millimeter large in diameter, but overall........a pretty good trick (for the money). I mean, this sells for about a buck....and you can teach it to any 6 year-old in about 1 minute.......so, these days, if you can get anything for a buck that even does what it claims to do....you're doing pretty well!
