Mini-Blog post #3

For my third mini project, i made ice cream. When making ice cream it is quite simple. The salt reacts with the ice to create an endothermic reaction. But there are a few simple items.

Needed items:
1. 1 cup of milk
2. a plastic sandwhich bag (preferably ziplock types)
3.1/3 cup of salt
4. 3 tsp of vanilla
5. 1/2 cup of sugar
6. ice
7. freezer ziplock
8. any condiments you wish for your ice cream

to do:
First you need a ziplock baggie. Then take the 1 cup milk and put it in the bag. After, put the 3 tsp of vanilla in the milk. Add the sugar and stir it around in the baggie. Make sure to securely close the baggie. Once that is finished, place the small baggie in a bigger freezer ziploc. put a couple scoops of ice and add the salt. Stir around in the big baggie, until the milk mixture frezzes and you have ICE CREAM.

scientific explanation:
There is no reactions in the milk mixture, but the main part of the reaction is the salt and the ice create an endothermic reation. Then, the endothermic reaction gives off large amounts of cold temperatures. This freezes the milk mixture and creates the ice cream.
