Tonight my family and I went to the Honolulu Festival to watch the fireworks display at Waikiki beach. This event was really important to not only me, but the city of Honolulu as well because the people who donated the fireworks display are the people of Nagaoka, our sister city in Japan. The fireworks or はなび remind me of my amazing experience in Nagaoka with my host family. This makes me want to go back to Japan again. The fireworks show was awesome. We were able to watch the fireworks show from the balcony of a hotel in Waikiki. The fireworks were many different colors and figures. One of the images reminded me of a Pokemon ball.
For fireworks there is chemistry, but also physics behind this wonderful spectacle. However, I will only discuss the physics in a fireworks display. Some of the important factors to a successful fireworks show are the relationships between vectors, velocities, projectiles and their trajectories, explosion forces and so on. For example, larger aerial shells produce greater initial velocities. Pyro technicians have to work with many different Physic equations for the fireworks to work. Here is a photo of the fireworks at the 2013 Honolulu Festival:
