FAQ Content
Dry ice is a great substance for performing “science experiments” with proper adult supervision.
In this experiment I placed a small amount of water inside a latex glove and added about 4 spoonfuls of dry ice, then quickly tied the end of the glove in a knot and hung it off the porch from an ornamental candelabra.
The most difficult part is handling the dry-ice safely. Ideally you and a helper should wear gloves. One holds the glove open while the other spoons dry ice into it.
Make sure if you try this at home that you and all spectators watch the expanding glove at a safe distance. When the glove bursts small fragments of dry ice may fly free and there is a risk of some hitting someone in the eye! You have been warned!
The glove expanded very rapidly as soon as it was tied closed. The size you see at the start of the video was reached in a few seconds (before the camera started rolling). However things slow down from there and the experiment was left unattended with the camera rollling before it finally burst well over 30 minutes later. This may be an anticlimax for young scientists. You can speed things up by squirting the glove with a little water to make the dry ice sublime faster or burst the glove with a sharp object (but be careful!). Note that if you put insufficient ice in the glove or your knot leaks a little then some gas may escape and the glove may never burst.
