Firework night has arrived. Five fireworks of varying colours were set off at different times.

Can you determine the colour of each rocket and at what time it was set off?

1. The Big Rocket was set off before the Appolo Rock, but after the Whiz-Bang.

2. The Appolo Rock contained no red and was not set off last.

3. One of the rockets containing green was set off at 7:45pm, this was not the Big Rocket or the Shooting Star.

4. The red rocket was set off after the blue rocket, but before the purple rocket.

5. The Exploder was set off exactly 30 minutes after the blue rocket.
