Project Inspired By:

This was an original idea, original to me anyway. Though I’ve never seen it done before, I’m not ignorant enough to believe I’m the first.

WARNING: Dry Ice is extremely cold! (-78C/-109F) and can cause instant frost-bite to exposed skin. Popsicles made using dry ice can be anywhere up to 5 times colder than regular popsicles and will stick to the tongue on first contact unless warmed first in a glass of warm water. This project should not be attempted without adult supervision and adequate training. Misuse, or careless use, may result in serious injury. Use of this video content is at your own risk.

Project History & More Info:

With dry ice being so cold, I simply wondered what would happen if we carved a groove in a chunk of dry ice and poured juice into it. Obviously it will freeze, but I wondered how long it would take.

For this experiment the juice took about 13 minutes to freeze completely solid. While that is impressively fast to make a popsicle, I actually thought it would have gone a bit quicker.

I suppose it took a bit longer because the cold wasn’t contained in an insulated container. The block was exposed to room temperature air, and in order to freeze the juice, the dry ice first had to freeze the bottom layer of the juice, then slowly work the cold up from the bottom. A slow process, and as you can imagine, the popsicle ends up being dangerously cold.

I dipped mine in a glass of warm water before trying to eat it so it wouldn’t grab onto my tongue :)

I am happy about the shape of the popsicle! It turned out great, and to get exponentially quicker results in the future, I might try placing a block of dry ice over top of the popsicle mould as well, then closing it off in a styrofoam container.

This was a fun experiment and the popsicle was delicious.
