Grandson David had a magnet in his hand as he walked by one of his cousin’s Christmas mobiles. He found the wires were magnetic, so we sat down at the table and played with it. David made it look easy to cause the stars to turn by moving the magnet in circles. If his hand went too close, the small stars jumped and glued themselves to the magnet. When that happened, we couldn’t stop ourselves from laughing. I tried it, and after a few moments, I handed the magnet back to the master mover.
Here is a photo in case you can’t see the video clip.
Our nephew, Christopher Pollock, is an artist, and he created the mobile shown here. I particularly like his mobiles and stick figures. This link to his blog https://christopherpollockart.com/tag/kinetic/ will take you to the kinetic area.
