Gandalf's Fireworks were created and designed by Gandalf. The fireworks include: Squibs, crackers, backarappers, sparklers, torches, Dwarf candles, Elf fountains, Goblin barkers. Some were rockets like a flash of birds, green trees that transformed into possibly Mallorn trees. And a red and gold dragon (possibly resembling Smaug). However the fireworks themselves are not magic.
