How to REALLY use fireworks in KSP...

Fireworks aren't actually just to look cool. You can blow stuff up with them! I know Matt Lowne said that you couldn't, and at first I thought so, but then I accidentally blew up one of the things around the launchpad. After that, it was just a bit of trial and error.
The Music is from Movavi Video Editor except for the last song, and I only know the name of the first one.
1st song: Splashing Around by the Green Orbs
Last song: Hyperfun by Kevin Macleod
