Lantis Fireworks is putting on the show.

Today, the guys spent the day fusing the explosives.

The show will contain mortars of varying sizes.

So, what can you expect to see this year?

"We have a heart shaped shell. We have a couple of smiley faces that will be up there, a bow–tie or two. So, just look for special things that are peppered throughout the show," said Neil Christensen, Lantis Fireworks.

If you're planning on watching the show at CSI city leaders recommend you arrive early.

North College Rd. will be closed at 7 p.m. on July 4th.
