Transcript of Adoniquinee Scott

QUEEN
Instructions

1.First we got the bowls and the indregients together.
Then we sat them all on the table to seperate.
.We place the dry ice in the bowl and add some water (it start looking like a spooky cauldron).
.We Soak the material in the soapy mixture and run it around the lip of the bowl before dragging it across the top of the bowl to form a bubble layer over the dry ice.
.We Stand back and watch your bubble grow

What Happening?



Dry ice is carbon dioxide (CO2) in its solid form. At temperatures above -56.4 °C (-69.5 °F), dry ice changes directly from a solid to a gas, without ever being a liquid. This process is called sublimation. When dry ice is put in water it accelerates the sublimation process, creating clouds of fog that fill up your dry ice bubble until the pressure becomes too much and the bubble explodes, spilling fog over the edge of the bowl. Dry ice is sometimes used as part of theater productions and performances to create a dense foggy effect. It is also used to preserve food, freeze lab samples and even to make ice cream

Items I use
•Water
•A large bowl with a lip around the top (a smaller bowl or cup will work too)
•A strip of material or cloth
•Soapy mixture for making bubbles (water and some dishwashing liquid should do the trick)
•Dry ice - one piece for a cup, more for a bowl.

Safety first! Be careful with dry ice as it can cause skin damage if not used safely. Adults should handle dry ice with gloves and avoid directly breathing in the vapor
