2 tablespoons Whipping cream
A cracker
Pinch of salt
Procedure
Step 1-Pour the 2 tablespoons of whipping cream into a small, clear-glass jar, with a tight-fitting lid. Add a pinch of salt. Toss a clean marble in, then screw the lid on very tight.
Step 2-Shake the jar until your arm is tired. Let your friend shake the jar. When your friend is tired, shake the jar again.
Step 3-Keep checking the jar. After a lot of shaking, you'll see the butter forming inside.
Step 4-Open the jar and take out the butter with a spoon. Spread it on a cracker and enjoy!
