# magic 8 activity
Welcome! This activity will help you create a magic 8 ball on the micro:bit. Let's get started!
Show a string to instruct the user how to play Magic 8! The magic 8 ball can only answer true or false questions.
```blocks
basic.showString("ASK A QUESTION")
```
Display the number 8.
```blocks
basic.showString("ASK A QUESTION")
basic.showNumber(8)
```
Create a condition for when the micro:bit is shaken. Then use the block `clear screen` to clear the 8 from the display.
```blocks
basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
basic.clearScreen()
});
```
Create a variable of type number called **randomNumber**. Set **randomNumber** to a random number with a limit of 2. Remember the random function in the math library, picks a random number from 0 to the limit, but not including the limit unless it is 0.
```blocks
basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
basic.clearScreen()
let randomNumber = Math.random(3)
});
```
Create an if statement for the condition `if randomNumber = 2`. If **randomNumber** is 2, display the string 'Yes'
```blocks
basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
basic.clearScreen();
let randomNumber = Math.random(3);
if (randomNumber == 2) {
basic.showString("YES");
}
});
```
Create an if statement for the condition `if randomNumber = 1`. If randomNumber is 1, display the string 'No'
```blocks
basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
basic.clearScreen()
let randomNumber = Math.random(3)
if (randomNumber == 2) {
basic.showString("YES")
} else if (randomNumber == 1) {
basic.showString("NO")
}
})
```
If **randomNumber** is not 2 or 1, it must be 0. This is the else condition. If **randomNumber** is 0, display the string 'I don't know'
```blocks
basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
basic.clearScreen()
let randomNumber = Math.random(3)
if (randomNumber == 2) {
basic.showString("YES")
} else if (randomNumber == 1) {
basic.showString("NO")
} else {
basic.showString("I DON'T KNOW")
}
})
```
Display the number 8 so users know they can ask the magic 8 ball another question!
```blocks
basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
basic.clearScreen()
let randomNumber = Math.random(3)
if (randomNumber == 2) {
basic.showString("YES")
} else if (randomNumber == 1) {
basic.showString("NO")
} else {
basic.showString("I DON'T KNOW")
}
basic.showNumber(8)
})
```
