Halloween FUN!

1. WHAT is it?Dry ice is the solid form of carbon dioxide (CO2) that has a temperature of -78.5∘C.
It may look like ice, but it does not melt! |
Unlike regular ice, it undergoes a process called sublimation, turning directly from a solid to a gas at room temperature without melting into a liquid. This property makes it useful for cooling, shipping, and creating fog effects, but it can be dangerous due to its extreme cold and the asphyxiation risk posed by the gas.
2. How to handle it?
Some places recommend to use gloves and goggles, but realistically speaking, as long as you are very careful, you will be fine.
The rule is to never hold it in your hand, but "hot potato" it.
More than 2 seconds will start hurting like crazy, so you will probably know when you make a mistake!

Your Stomach
I'm sure you would like to eat the rock, but there are many reasons not to do it.
Besides the 3rd degree frost burns!
Let's get a balloon and add a little bit of very hot water with the extra beaker, then drop a rock inside and quickly tie it.

Hot Volcano
- Grab a piece of paper and a beaker.
- With a second beaker, grab a few rocks of dry ice.
- Roll the paper in a way that forms a cone.
- Put hot water in the beaker; about 100 ml should do the trick.
- Make sure the opening of the cone is about an inch, but not much bigger. Tape the cone so that it covers the whole opening of the beaker.
- Drop a rock in it. :)
