It’s just a shame that this person isn’t rocking a full Doctor Strange getup to really sell it.
Strangely, the coolest part is actually how the spell finishes, with it glowing brighter before fading out into magic dust.
This is incredibly creative and shows great attention to detail.
I suppose one could walk around twirling sparklers, but this seems like a safer, more efficient and ultimately cooler way to simulate Doctor Strange’s spell casting.
