Dry Ice Crystal Ball Bubble
AHMAD SALAH
Abstract
Steps
Explanation
There are 3 states of matter, solid, liquid, and gas, each
having different physical properties
When you combine warm water and dry
ice in the container, the dry ice quickly
sublimates and turns into gas. The gas
forces itself out of the end of the
container's tubing. If you dip the end of the
tubing into some extra strength bubble
solution, the clouds of carbon dioxide gas
will form large, smoky Boo Bubbles.
Add a piece of dry ice. The
dry ice will make bubbles in
the liquid.
Needed Materials
 Dry Ice
 Warm water
 Bowl
 Towel/rag
 Soap
Spread a film of bubble solution
around the lip of the container.
Normally, melting ice goes from a solid to a liquid. Through
a process called sublimation, a solid can go straight to the
gas phase, skipping the liquid stage.
Dry ice is able to go from its solid form to a gaseous CO2.
Dry ice is a solid piece of carbon dioxide that sublimates
straight to CO2 gas when heated.
The vapor that is produced when dry ice mixes with water
is actually water vapor that condenses out of the air when
the air is cooled by CO2 gas.
Steps
Pour some water or
tonic water into the
container.
Use your hand or a piece of paper towel that has been wetted with bubble
solution to smear bubble solution across the top of the container.
This can also be seen when we exhale during cold
weather.
By running the soapy towel over the bowl, this creates a
barrier that is able to trap the vapor from escaping.
CH4+2H2O → CO2+4H2 CH4
The vapor has no choice but to move up, therefore creating
the bubble effect.
The vapor will keep expanding until too much pressure has
accumulated that the bubble breaks.
