For sometime now I have been keen to build some explosion markers. The following tutorial is nothing new but might help people to build their own.
The cost for 12 of these I reckon comes out less than a tenner and they look great.
These started off life as a tealight, you can pick up a dozen of these flashing battery power ones up on ebay for less than £3
Next up I had some old polyester cushion filler I was using as smoke in my games. These were cut into rectangles with one side the circumference of the tea light. Mine stand about 12 cm tall.
These were glued using an all purpose glue - messy job so recommend you war latex gloves.
Leave overnight to dry. Once dry tease out the filler into a plume shape. This is very easy.
Take a good old black spray and....spray. Once dry (can take some time)...spray again.
Pull out battery tab and bobs your uncle...
Here you can see my finished effort sitting on top of a Sherman tank (solido version)
Total time to build (excluding drying time) about an hour.
