Watch: This is what the biggest firework in the world going off looks like

This is something you definitely won't be seeing come midnight on New Year's Eve.

The Katakai Fireworks festival takes place every September and is over 400-years-old, and sees some of the largest and most elaborate fireworks displays in the world, and ends each year with the largest firework in the world, this 48-inch shell that just keeps on giving.

For scale, here are other normal fireworks growing in size from 2 inches all the way up to the 48-inch one that's only seen at Katakai. Remind us again why we're not allowed have these here?
