According to YouTuber Crazy Russian Hacker, you can make vanilla ice cream in a matter of minutes.
So, start by mixing the vanilla extract, milk, half-and-half, and sugar.
Pour your mixture into a ziplock bag and seal it, making sure there's as little air inside as possible.
Fill up the other ziplock bag with ice and pour salt in it. Shake it up a little.
The salt makes the ice REALLY cold.
Place the ziplock with your mixture into the ziplock with the ice and seal it.
Put on some protective gloves and shake the whole thing for about five to 10 minutes.
Crazy Russian Hacker says, "Safety is number one priority."
