On Tuesday we had a visit from, Joe, a 3M Science Wizard. He taught us about the states of matter and cryogenics. We were able to complete many experiments with the liquid nitrogen he brought! He turned a banana into a hammer, smashed a racquetball into pieces, and crushed a balloon with the air still in it! To cap it all off, he made us crunchy marshmallows! What a treat!
