A similar effect to Tenyo's Silk Serenade by Pavel but the method is different. This method copies Tricks Co. LTD 1976's release entitled Color Rhapsody. In fact, this newer method became the standard for the actual Color Changing CDs that came afterwards. 3 Black 45 RPM Records are shown on both sides.. Place one into the sleeve, when it emerges, it has changed colors! Repeat three times, produce 3 different colors. Red, Yellow & Blue. Basic instructions printed on the records.What they don't tell you is to stack them so each color corresponds to the gimmick. Show both sides. insert one record into the sleeve (actually pass it completely through the sleeve. But once the record reaches the middle, you leave the gimmick inside the sleeve only passing the record part all the way through. Not insert the record again but this time reverse the order of the record and the gimmick, so when they both emerge, you can show the record on both sides, but in a different color.

Please note records are plastic coated paper. Record sleeve is a bit bent. But still works fine.
