We had some fun with this fishing activity. I tied a magnet onto a string and then onto a dowel. The magnetic objects were placed into the water one by one. My daughter observed that the clothespin was the only one to float.
After a few turns, I added some rocks to the bottom of the container to make the fishing a little more challenging.
Here are the rocks and magnetic objects we used.
We dried things off and put it on the shelf ready for next time.
