Equal and opposite reactions, a la J

J: The floor is hard because when I fall, it rips holes in my pants.

 Got to love Newton's 3rd Law explained by a 4 year old, or maybe his own definition of the hardness scale. John has been scratching rocks with other rocks to try to explain hardness. Either way, I found it an amusing conversation this morning.


  1. I love that he is already scratching rocks to test hardness. What a smart kid! And his quote is adorable!

    1. Oh, John, my husband, has been showing J about hardness tests with rock scratching. J can totally tell you about which rock is harder at the playground though thanks to those 2 second lessons. Our material science prof would be so proud.
