Each of our dry ice blocks are the shape of a square textbook: ten inches long, ten inches wide and two inches thick. Each dry ice block arrives wrapped in a plastic bag, for easy handling.
Depending on what you’re using the dry ice block for, it may be necessary to break a block, to obtain smaller dry ice pieces. This is especially the case when using dry ice to pack breastmilk or create fog.
Always handle dry ice with care and wear gloves whenever touching it. An oven mitt or towel will also work if gloves are not handy. If touched briefly, dry ice is harmless, but prolonged contact with the skin will cause injury similar to a burn.
Find more safety information on our dry ice safety page.
Leave the dry ice block inside of the plastic bag, then from around waist height, drop the bagged block onto the ground. A hard surface like wood floor or concrete works best for cracking the block.
It’ll only take one drop to break the block, but you can repeat as necessary until the dry ice pieces are the size you need.
