Somebody should teach Klee that you can't use high explosive gunpowder to make sparklers.
Funnily enough, conventional sparklers are indeed made from a more explosive type of 'gunpowder' (a flash powder variant, usually). Only reason why they don't go kaboom is because of how they are bound and formed into sticks. When people repurpose them... things get ugly.
The "morning glory" type sparkler they're using here has a different construction, consisting of a pyrotechnic mix poured into a paper tube (usually a few different mixes, layered inside the tube for different colors). This uses a different, less 'explosive' mix, though it still features similar ingredients (just in different ratios).
If you take a conventional sparkler compo mix (meant to be wetted and used to coat a metal wire), and pack the loose powder into a "morning glory" tube... well it's gonna go kaboom. It's basically an oversized M-80 by that point.

The 'can't' in my comment was suggesting you shouldn't (because of the reasons you stated, I simply didn't put that reason so people won't try and...well, ended up losing their fingers), but yes, that's how people in SEA coastal region made fish-bombs, IIRC.
