I’m working on a couple projects for Halloween. I like the spooky, ambient effects best, and I’m really not into anything gory — gore is totally overrated and overused during Halloween.
Here are some of my ideas:
I really like the effect of the Fireflies in Pirates of the Caribbean. They may not seem Halloweeny, but they can add a nice ambient atmosphere. The Fireflies are probably best when viewed at a distance.
I haven’t actually tried this, but I’ve read of similar setups elsewhere. It will require some experimentation.
- 12v worth of batteries & battery holder
- 12v transformer
- Low voltage LEDs (White or Ultraviolet!!!)
- Plastic or paper for the blinders/wings, matte-black
- Thin gauge magnet wire (lightly insulated and painted matte-black)
- A board to attach it too
- A fan
Solder the transformer, wire & LEDs together. Arrange the wires in a spring-like shape or attach them to the board with springs.
Put a blinder on the LEDs so the light is blocked from some angles and visible from other angles. This will make the fireflies appear to blink.
Put the setup in front of a fan. The blinders will act as wings and catch the draft provided by the fan. The spring on the wire will make the fireflies appear bob up and down.
Now you have wiggling, bobbing, blinking fireflies!
There are some other instructions here:
This project is pretty simple & low-cost, but it’s not well known. You can do a bunch of different stuff with ths idea.
- Thin fabric like gauze or muslin
- some spray-on laundry detergent that contains “whiteners” (Phosphorous, etc).
Cut the fabric; spray the laundry detergent onto the fabric. Hold the fabric under the blacklight. The whiteners in the laundry detergent are actually chemicals like phosphorous or zinc sulfide that glow brilliantly under blacklight.
Use springs, string to hang them. A fan can make them bounce. Helium balloons can make them float around very well.
