So a couple of people asked me about my last post, and how to ACTUALLY MAKE ice cream using duct tape.
First, you need two metal coffee cans. A big one (4lbs or so) and a small one (1lb). Of course, they don't actually need to be "coffee" cans. Anything with a replaceable top will do, but the important thing is for the outside one to be able to roll on the ground. By the way, if you don't feel like buying a can of Maxwell House, Pirouline cans do quite well and taste better.
First, fill the smaller can with the following:
-two pints whole milk or cream
-two tablespoons vanilla
-1 cup sugar
Now, close the small can and seal the cover tight with duct tape. Put the small can into the big can, and pack the big can with ice cubes. Add about a cup of rock salt (the kind you use on your driveway, I'm sure you've got some right now). Close and seal the big can with duct tape as well.
Now, have a seat on the floor with your kid proceed to roll the can back and forth for at least 20 minutes. This mixes things up quite nicely. Depending on the warmth of the room, it may pay to open the big can and add more rice/salt mixture again.
After 20 minutes, if the planets have aligned, you've got yourself some fine vanilla ice cream.
