I remember when we were young each year we'd travel all the way into the city and spend hours setting up a picnic to secure the perfect spot to watch the fireworks at Southbank. We looked forward to it all year. We loved all the different colours, shapes, sizes and the fact that they appear out of nowhere. They're just so magical, especially for little kids.
Unfortunately fireworks are also quite loud, so unless you want to invest in a pair of headphones, sometimes it's best to watch them on the TV not up close, particularly for children with sensory issues. My girls don't like crowds and aren't fans of loud noises so we haven't ventured out for live fireworks yet, but we have found another way to join in with fireworks celebrations. We create fireworks salt painting process art at home.
Fireworks salt painting is a great process art activity for preschoolers, and a great classroom activity too. It's also a great stem activity, combining art process and science concepts like absorption. It can get a little bit messy though, so if you're doing it inside you'll probably want to use a tray and a splash mat or plastic table cloth. Art smocks might be a good idea too if the kids get a little too excited by glue and painting. Alternatively set it up outside and just let the kids wear old clothes you don't mind getting dirty.
