In this tutorial, Science Bob shows us how to do a science experiment with dry ice. First, take a block of dry ice and place a quarter on top of it. Make sure you are using rubber gloves when you do this, it's dangerous to touch gloves with your bare hands. When you press the quarter down, it will cause it to vibrate very quickly. You can put any type of metal on top of the dry ice and it will make different noises. This is only one of the many things you can do with dry ice. You can also use this as a decoration for Halloween, since it looks like mist or fog.
