Waikiki and other parts of town is expected to be packed this weekend.

The 24th annual Honolulu Festival kicked off Friday. The Three day event features programs and activities all over town, many of them happening at the Hawaii Convention Center to showcase traditional dance, along with arts and crafts.

Capping off the festivities, 1,400 shells will be lighting up the sky in Waikiki. A fireworks show by Grucci is set for Sunday at 8:30 p.m.

It's no ordinary show. Grucci says this one is the biggest it does all year, better than New Years and the Fourth because the fireworks are made in Japan and is some of the best products that exist.

"The Japanese very meticulous about their shells, beautiful colors, very expensive shells so it's a very expensive show that the city of Nagaoka has donated to Honolulu," Tom Likos, Fireworks by Grucci said. 

The show is set to last for 20 minutes, that's more than double the norm.

They'll be shot from boats just off of the Royal Hawaiian Hotel and it'll be synchronized to Japanese and Hawaiian music on 105.1 KINE.
