PERPETUO! VINTAGE WOOD KINETIC ART SCIENCE PHYSICS TOY

perpetuoANOTHER WEIRD AND RARE SCIENTIFIC-INSPIRED AMUSEMENT DEVICE ALONG THE LINES OF THE ORBI AND THE FLURRY, PERPETUO IS A WOODEN KINETIC TOY THAT USES RUBBER BANDS AND THE LAWS OF PHYSICS TO MAKE IT DO IT'S THING. WHEN ASSEMBLED PER THE INCLUDED INSTRUCTIONS, AN ARM WITH A BALL AND STRING WILL SWING AROUND 360 DEGREES, THE BALL AND STRING HIT A VERTICAL POLE AND THE SWINGARM STOPS. THE BALL AND STRING WINDS DOWN THE POLE AND BACK UP. WHEN IT REACHES THE TOP, THE SWINGARM IS RELEASED AND SPINS AROUND AGAIN, REPEATING THE PROCESS UNTIL THE RUBBER BAND "MOTOR" HAS COMPLETELY UNWOUND. THE KIT ALSO INCLUDES A SHORT ESSAY ON THE THEORY AND PHYSYCS OF PERPETUO. THE KIT IS COMPLETE AND IN EXCELLENT CONDITION. THE RUBBER BANDS ARE NOT YET BRITTLE, BUT THEY ARE OLD AND MAY NEED TO BE REPLACED EVENTUALLY. THIS STRANGE ECO-FRIENDLY DINGUS WAS MADE BY SOLAR WIND OF FT. COLLINS, COLORADO.
