The prophet Elisha did some pretty cool things. You can read his story in the late chapters of 1 Kings and early chapters of 2 Kings. I want to look at what happened in 2 Kings 6:1-7. It's a really short story, so I'll share the entire passage:
"The company of the prophets said to Elisha, 'Look, the place where we meet with you is too small for us. Let us go to the Jordan, where each of us can get a pole; and let us build a place there for us to meet.' And he said, 'Go.' Then one of them said, 'Won’t you please come with your servants?' 'I will,' Elisha replied. And he went with them. They went to the Jordan and began to cut down trees. As one of them was cutting down a tree, the iron axhead fell into the water. 'Oh no, my lord!' he cried out. 'It was borrowed!' The man of God asked, 'Where did it fall?' When he showed him the place, Elisha cut a stick and threw it there, and made the iron float. 'Lift it out,' he said. Then the man reached out his hand and took it."
There really isn't a whole lot to say about this passage. I think it's really wild that Elisha made an iron ax float. And how weird is it that he made it float by cutting a stick and throwing it in the river?! This is just one of those "whoa" moments where you're so impressed, there just isn't a whole lot to say except that we serve an amazing God.
