Items sometimes spin rapidly when you place a bed on top of it.

You probably know that a good way to mine netherite is using beds to blow blocks up, which can reveal ancient debris. But I dropped an item I didn't need into a lava waterfall nearby, and accidentally threw it on another nearby block. I didn't notice that, before I knew it, I had placed the explosive bed onto the item. The drop began to spin really fast, instead of being pushed somewhere else( the scene is in an enclosed space deep under the nether).
