Resin Light Up Color Changing Unicorn Horn Circlet

This was a project inspired by my sister's plan to be a unicorn for Halloween. After much deliberation and planning and purchasing of supplies, I commenced the creation process which took about a solid week to get it wearable.
I have included a video of the color-changing effect!
If the video doesn't work here I also posted it on youtube:
