Hi! I used the large 2 gallon glass jar but you could use any size. As far as I know you can use both glass or plastic. Its actually super easy to make and fun too! Just don’t touch the dry ice with bare hands or it will burn you. The lidded jar I used is linked in the post (just click on the images and it will take you directly to the link) and there is also one that is the same 2 gallon size that has a spout on it too. Eveything is linked throughout the post and at the bottom so scroll down to the bottom to see all the options.
