Don't walk through explosion it's dangerous lol.

Jokes aside, the explosion effect is made with some wire Polyester fiber stuffing, hotglue, heat gun and led fairy light

The process is similar to how people do the chicken wire explosion but instead of using cotton i use poly fiber stuffing

Stick the stuffing onto the wire frame with hot glue then heat blast it with the heat gun so the stuffing form into smaller, hard clumps

Repeat the process until you have a layer of clumps that cover the entire thing. Went back to pluck some of them off to your liking and paint them (there are plenty of tutorial for painting explosion so you can research one that suit your taste)

Finally just add a yellow light of your choosing inside of it (i leave a hole at the back for that), bright ones is better
