Dry ice (carbon dioxide) will not fill the ice cream cart with water on thawing. Ice formed by frozen water would fill the cart with water on thawing.
Cut the ice cream into bars and put in Popsicle sticks. Dip them in chocolate and show that is freezes on the ice cream bar. Roll it in chopped peanuts for show. You could always show how ice cream used to be made in a cranked container with the ice cream mix in the center portion and rock salted ice around it freezing the liquid. Explain how that works to the judges. Both would get attention if not prizes.
because as it melts, it causes a visible vapor which resembles smoke. it is also relatively cheap to produce. it is also better to use dry ice if your walking into it because then it will not hurt your lungs
Dry ice is frozen carbon dioxide. Carbon dioxide can cause suffocation, and is not flammable (often used in certain fire extinguishers).
Dry ice can be used for tons of stuff. Here is a list of some of the most popular uses:Dry ice blast cleaningMedical cleaningMedical transportationExperimentsKeeping food fresh in power outagesShipping of food across the country
Use modeling clay to shape a volcano, then fill it with water and when you are giving your presentation, drop dry ice in it, it will begin to make fog.
To help them stay cold for people to enjoy during the summerCarbon Dioxide (or dry ice) keeps the ice-cream mixture cold enough to be a semi-solid... otherwise it would eventually melt into a creamy 'mush' !
so the ice lasts
You don't. To make ice cream you want to make it with ice cream salt.
no
Dry Ice is made up of a chemical. When exposed to air it dissipates. The more the air gets to it the faster it disappears. To make you dry ice last longer, just keep your container closed and make sure it is air tight. The Ice Cream Man

Dry ice can keep ice cream frozen for several hours, typically between 4 to 10 hours, depending on the quantity of dry ice used, the insulation of the container, and the ambient temperature. For best results, using about 5 to 10 pounds of dry ice for a standard cooler-sized container can help maintain the ice cream's frozen state longer. It's important to handle dry ice with care, as it can cause skin burns.
Solid carbon dioxide is called dry ice, it is created by compressing carbon dioxide and chilling it, so it is very cold. When it heats up, it does not melt into a liquid, but straight into a gaseous form. This is called sublimation.That's the common name for frozen carbon dioxide.("dry" because it turns into a gas at room temp rather than a liquid.)
It does not melt into water like regular ice. It sublimates to a gas when it warms up, making it a lot less messy to keep next to your ice cream.
the ice cream will get dry and sticky and will smell sour
depends on what ice cream it is... but if its normal whippy ice cream... then ice cream will melt faster
One creative way to make refreshing summer treats using dry ice is to create dry ice popsicles. To do this, mix your favorite fruit juice or soda with chunks of dry ice in a mold. The carbonation from the dry ice will create a fizzy and refreshing popsicle. Another idea is to make a dry ice ice cream by mixing cream, sugar, and flavorings with dry ice in a bowl. The dry ice will freeze the mixture quickly, creating a creamy and smooth ice cream. Just be sure to handle dry ice carefully and follow safety precautions when using it in food preparation.
