Making Dry Ice Is Fun!

by Michael M.

Dry ice is solid carbon dioxide, a gas, under normal conditions. It’s dense than regular ice (mostly water) and doesn’t melt—it sublimates into CO2 gas. You can make dry ice at home by putting some regular ice in an empty soda bottle and then adding dry ice pellets. It should start to evaporate almost immediately!

You can also use a dry ice making machine for it.

Dry ice is solid carbon dioxide.

The following is true of dry ice:

  • It’s solid carbon dioxide.
  • Carbon dioxide is a gas at room temperature and pressure.
  • Carbon dioxide is also known to be a greenhouse gas (a factor that contributes to global warming).
  • Carbon dioxide is used in fire extinguishers because it makes things extremely cold.
  • If you don’t want your soda to taste funny after adding the dry ice, ensure it’s completely frozen before mixing it with your drink!

Dry ice is denser than regular ice.

Dry ice is solid carbon dioxide, which is denser than water. This means that anything you put into a bowl of dry ice will become denser than before you put it there. When something becomes denser, it sinks; that’s why your bottle of soda sinks when you pour water into it.

Putting an object like a balloon or ping-pong ball on top of some dry ice will sink right through the frozen CO2 and down into the container below!

Dry ice is not water.

Dry ice is not water. It’s solid carbon dioxide and can be used as a food preservative or an ice substitute.

Dry ice does not melt; it sublimates.

Dry ice is solid carbon dioxide, but it doesn’t melt. It sublimates or turns directly into a gas. That’s why you can use dry ice to make fog machines!

Dry ice is not water; it’s much denser than regular ice and has many more uses than just making things cold. For example, if you want to make an icy drink without diluting it with water, put your glass of juice on top of some dry ice for a few minutes and then stir before serving!

You can make dry ice at home!

Making dry ice at home is easy! You only need an empty soda bottle, a fire extinguisher, and styrofoam.

First, take your dry ice (you can buy it online or at the grocery store) and put it in the bottom of your empty soda bottle. Next, twist on some foil over the top so that it covers the opening of your soda bottle. Then, put that into a container filled with hot water—the hotter the water gets, the faster your dry ice will change into carbon dioxide gas! The heat from inside of this container causes most of its liquid to be drawn out by evaporation until there’s nothing left but gas molecules trapped between two layers: one made up entirely of carbon dioxide gas molecules floating upwards towards their kind, another layer comprised only by non-carbon dioxide gas molecules all floating downwards away from theirs (because of gravity). Finally, put some styrofoam underneath this container so all those gases don’t escape through cracks between floors or walls before they can cool down enough AFTER being turned back into solid form again as CO2 crystals, which means less waste overall since there aren’t any liquids left behind when making something like bread cubes – only water vapors will remain after baking them for about 20 minutes at 350 degrees Fahrenheit!


The next time you’re making a dessert, try adding some dry ice! You can also use it to make your fog machine or even freeze a drink. Dry ice is interesting and fun—and it’s easy to make at home!
