To make this Spinning Magnetic Star you need two pieces of corrugated board, a cut metal bottle cap, paper circle with spiral, two cycle spokes, a ring magnet, scissors and glue. The ring magnet will easily stick to the steel spoke. Take two strips of corrugated board. Weave both spoke through the boards so that they make a long and narrow rail track. Tape both spoke heads to fix them to the card pieces. Now by bringing both card pieces close and stretching them you can change the length of the track. Cut a metal bottle cap into a star shape. Punch a small hole in the centre. Stick the ring magnet in the center of the metal lid. Then stick a white circle on top of the magnet. Stick a circular spiral on top of this circle. Now place the lid between the tracks. Because of the ring magnet the lid will stick to the track. The center hole in the lid will be between the tracks and will act as a guide. Now the toy is ready. On moving the card pieces back and forth the track length will increase and decrease. This will make the metal star spin clockwise and anti-clockwise. The motion of the metal star will appear very intriguing and will be a source of great joy!
