For this post I thought I’d try something a little different. I’ve created 3 videos which together describe how to create a severed hand in a jar display for halloween. My daughter TJ helped with this one by doing the voice over for the first 2 videos.
- Making a 4.5V battery pack
- Making glow water
- Building the UV light source and putting everything together
Lastly, the photo on the left shows the finished board with the 4.5V battery and the LEDs. This might be a useful reference when viewing the 3rd video.
