Brexit
Whatever your politics, this one delivers. Brexit fans 25 shots out and finishes inside five seconds, all coloured stars and crackle in one fast hit.
It's a dump cake from Celtic, which means the whole fan goes up at once rather than tube by tube. Blink and you'll miss it, so get everyone watching before you light the fuse. Rated F2, a garden firework: keep spectators at least 8 metres back for safety.
Fire it as your opener: one huge hit to grab the crowd, then on with the show. Unlike the namesake, there's no dragging it out.
