+create a snowflake fall animation #animation#forever #docs
+
+This is the answer key for the [snowflake fall quiz](/microbit/lessons/snowflake-fall/quiz).
+
+## 1. In reference to an animation, what is an "interval"?
+
+The number of milliseconds to pause after each image frame.
+
+## 2. What is the interval of the animation?
+
+```
+basic.showAnimation(`
+. . . . .
+. . # . .
+. # # # .
+. . # . .
+. . . . .
+`, 400)
+```
+
+## 3. Write the code to allow this animation to never stop displaying on the BBC micro:bit

+```
+basic.forever(() => {
+    basic.showAnimation(`
+. . . . .
+. . # . .
+. # # # .
+. . # . .
+. . . . .
+`, 400)
+})
+```
+
+## 4. Write the code to create a forever loop that shows an animation of these images. Change the interval from 400 to 800 to make the animation go twice as slow!
