Delaware residents saw a free -- albeit short -- fireworks display around 6 p.m. Monday, Nov. 18, when the city played host to a test of 12 different-sized firework shells.

The test was conducted by Ohio Wesleyan University and the Ohio Machine, Ohio's professional lacrosse franchise, to see which type of fireworks shell would be most effective. Shells were shot from the city's usual launching area off Cherry Street.

"They were interested to see what size shell would be needed to be seen over the tops of trees that have obstructed views in the past," said Lee Yoakum, Delaware spokesman.

Residents were alerted in advance of the test through social media and other mediums, and Yoakum said the city did not receive any complaints or calls from concerned individuals during the short display.

He added the city was involved in the testing only because of its experience with pyrotechnics, and that the Delaware Fourth of July fireworks show would not be altered this year due to the testing.

"We always shoot fireworks from that location and will continue to do so," he said. "Our fire department is experienced at launching fireworks and working with this fireworks company."

Testing fireworks in November may seem odd, but Hamburg Fireworks Displays, a Lancaster company that Delaware has used for its displays in the past, has virtually no availability during the summer because of other events.

The largest shell tested was a six-inch shell, although an eight-inch shell is available. Yoakum said an eight-inch shell obviously would be high enough, and that testing the other 12 sizes yielded information the Ohio Machine would use to determine which was best.

While the tests won't cause changes in Delaware's future Fourth of July shows, Yoakum didn't rule out larger effects.

"Potentially, we might have larger shells, which would be neat to see and fun to watch," he said, "but that's about it."
