Being a chemistry geek doesn't mean you can't have fun!

Step 1: Gather Ingredients

Gather ingredients and necessary tools:
4 cups whole milk
2 cups heavy whipping cream
1 tsp vanilla
1 1/2 - 1 3/4 cup sugar
1-2 liter Liquid Nitrogen  (CAUTION!!!!!  Careful handling must be used to avoid burns)

Metal bowl
Metal mixing spoon
Bowls and spoons

Step 2: Add Ingredients to Metal Bowl

Add all ingredients, excluding the liquid nitrogen, into a large metal bowl

Step 3: Add Any Desired Mix-ins

Add desired mix-ins to the bowl.  These can include candy bars, fruit, jam, chocolate syrup etc.

Step 4: Mix Ingredients in Bowl

Mix all the ingredients in the bowl until the sugar has dissolved completely.

Step 5: Add Liquid Nitrogen

Pour the liquid nitrogen slowly into the bowl while mixing.  Add in intervals to avoid spillage and to make sure the mixture is completely frozen

Step 6: Mix Vigorously With Metal Spoon

Mix the ice cream vigorously with a metal spoon.  This will smooth out the ice cream into an edible and recognizable substance.
