When you combine dry ice and ethanol, it makes a super-common cold liquid you tin utilise to freeze things solid. While scientists employ ethanol and dry ice baths for chilling chemicals, yous can easily make one at home to see how objects react when they're frozen. Later on you mix the water ice bath, it will stay around −77 °C (−107 °F) until the dry ice sublimates. Just remember non to touch the dry ice or ethanol with your bare hands since information technology can cause frostbite.

   Wait for the ethanol to finish bubbling to make full the rest of the bath. It'south normal for the ethanol to start bubbles as it cools down. As the ethanol gets colder, the bubbles will get slower or go away. Slowly add together in more ethanol until the container is most ⅔-total so you tin easily submerge items in information technology.^[5]

   • The new ethanol will bubble likewise as you lot pour it in, then be careful that it doesn't spill over the edge of the container.

   • Avoid using erstwhile food containers for storing used ethanol since they aren't acceptable for storing chancy waste material.
