Sparklers are that firework that always seems great in theory, but as soon as you light one (after holding over a flame for the better part of a minute) you realize that maybe your childhood self made them way better in their mind.
It turns out it’s a numbers game. One sparkler isn’t anything special, but as Slivki Show demonstrates, upping that number to 10,000 completely changes the game. Instead of a puny spark that dies out in about 30 seconds, you get a volcano of sparks that threaten to burn an entire field.
