Â Â Â Â Imagine a little nest with a baby bird in it flitting around anxious for mom to come and drop a worm. This is a really cleaver use of a magnet.
Â Â Â Attach the magnet to the shaft of a toy motor with some epoxy and then attach a flat head screw to the magnet. Try to keep the screw straight with the motor shaft. You could use a toy gear motor if you don’t want it to flip around so fast. Mount the motor on a base and point it at an angle towards the top of a rod which is also mounted in the base. Now I just made a bird as an example. There are lots of things you could have bob around at the top of the rod. Make some kind of pivot joint at the top of the rod and then wind a steal wire all around from that point down to the motor.
My explanation won’t do it justice. You’ll just have to see the video.
