This is the StreTching Rope trick -- not the Streching Rope trick as it says on the label.  No spell checker on their label design machine, I guess.   Why it is "of Prussia" is anybody's guess, but it does seem like there are a lot of magical ropes and beads and things in Prussia.   The routine feels like something that Pavel might have invented back int he 1970's or 1980's, but this version is part of Mak magic's imported magic line-up.

The effect is simple at first.   Two BLUE ropes are shown, one short, one long.  Then the two ropes are the same size.  then the two ropes magically become one long rope, about 5 feet long.   But then things seem to spiral out of control, as the one long rope starts to stretch (or is it strech?) longer and longer.   It keeps getting longer until it is about 20 feet long.

When played as if the magician has lost control and the rope is growing longer than he wants, and he is powerless to stop it... well, that presentation gets big howls from any kidshow audience.

The trick requires that you wear a jacket, with a pre-show set-up.  But it is not complicated to set, and once set, you could do your whole show without any bother from secret set-up. 

Ropes and gimmicks are nice quality, and the BLUE rope is good looking and very visible.

Brand new with instructions.   List price on this was about $35-$40.   I got a few at a great price, so you can get it here for less.
