I have a set of hot coals prop I have made (Using Great Stuff and orange lights). I want to have the lights flicker like fire, does anyone have a plan or easy method of making the lights flicker like fire? Thank you so much!
As someone who burns wood for heat I'd say that coals shouldn't flicker, they generally have a steady glow.
However, if you still want flickering, are using LED lights and still have access to a bulb, you might be able to add a flickering LED to a series for optimal fire effect (similar to a LED candle). If you're handy with electronics you might even be able to wire it in without access to a socket
If you're using regular lights and have access to a bulb, you can add a blinker to turn a strand into a blinking set. In case you don't know what I'm talking about, they're clear bulbs with a bit of red at the tip and can easily be found in any store that sells Christmas lights.
