This is a pencil with round magnets on it, stacked so that they will repel each other. The preschoolers love to take them off, and put them back on again to see if they will attract or repel.
Do you remember these little Wooly Willys from your childhood? I sure do! My parents used to take us on long cross-country car trips, and my mom would bring little toys to entertain us. The Wooly Willy was always my favorite! I found these mini versions at the party store, and they are a fun addition to the science center.
Get those magnets off the fridge and have fun playing and learning with your children today!
