# snowflake fall quiz answers create a snowflake fall animation. 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 ![](/static/mb/lessons/snowflake-fall-0.png) ``` 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! ![](/static/mb/lessons/snowflake-fall-1.png) ![](/static/mb/lessons/snowflake-fall-2.png) ``` basic.forever(() => { basic.showAnimation(` . . . . . # # # # # . . # . . # # . # # . # # # . # . # . # . . # . . # # . # # . . . . . # # # # # `, 800) }) ```
