This is at the Falls of the Ohio. I had a whisk, steel wool, and wire and it was spun in a circle behind my friend. I love how the sparks are just flying all over the place. 

This is a tree down by the Ohio River on the Indiana side. There is an ombre glow from Louisville. I like how you can see the stars, even though most of the time you barely can see them due to city light pollution. 

I had my shutter open for 5-8 seconds and then moved the sparklers in a random pattern. I like how it came out all swirly.
