If you’re having a Halloween gathering this year, the best way you can take it to the next level is with dry ice. Dry ice is frozen carbon dioxide (-109.3 degrees F) which turns directly from a solid to a gas. Adding it to hot water creates a fog that is perfect for making your Halloween party all the spookier. Dry ice can be picked up at most ice carriers, or you can find it online. You can even buy a Dry Ice Maker and produce it yourself.
To create fog with dry ice, simply add it to hot water. Once the water gets to about 40 degrees however, fog production will stop. When making fog with dry ice, it’s a good idea to keep a kettle of hot water simmering on the stove for when the water cools down. A great way to make a dry ice fog generator is to fill a crock pot with water and dry ice. It won’t be able to keep the water hot forever, but it will definitely take longer to cool down. These can be places behind decorations to create an eerie mist.
A great decoration to make with dry ice is a smoking cauldron. Simply fill up a cauldron with warm water and dry ice to create a prop fit for a witch’s lair. For added spookiness, you can toss in a glow stick.
Fog is also a great addition to one of the most classic Halloween decorations, the Jack-O-Lantern. Carve out your pumpkin and add a battery powered light or glow stick. After that, simply add a container of hot water and dry ice and watch the mist roll out of your pumpkin.
Billowing Punch Bowl:
Another classic use for dry ice is to create a smoking punch bowl. For this you’ll need two bowls, one going inside the other. Fill the larger bowl with warm water and dry ice and place a smaller bowl filled with punch inside. This creates a punch bowl that billows out mist.
Never touch dry ice with your bare hands, it is extremely cold and can cause freeze burns.
If using indoors, provide adequate ventilation. Breathing in too much carbon dioxide is hazardous.
Don’t store dry ice in an airtight container. As it converts from a solid to a gas, it can cause the container to explode.
