A report back. Yesterday I did a static grass workshop for members of my local club. Static grass is not readily available here and the electric flyswatters have only just started to appear in local supermarkets.
We found that we got good results with a flyswatter with FRESH batteries, this is important because the flyswatter seems to go through batteries very quickly. We had to hold the flyswatter close to the fibres to make them stand up properly. I made an earthing "pin" to go into the glue out of a strip of brass.
The Noch puffer bottle only seems to work as a very expensive dispenser and none of us could get very good results with it.
The star of the show was the balloon! After using the flyswatter I went over the grass with the balloon. The swatter + balloon combination worked as well as a Noch Grassmaster that someone had brought along.
I added a pinch of salt to the water I used to water down the PVA glue. If too much salt is added the glue will dry opaque. I have no idea if the salt makes any difference but a small amount doesn't do any harm.
As mentioned by a previous poster, weather does make a difference and getting a good static charge in damp weather will be more difficult.
As an N gauge modeller I prefer the medium length fibres even if they are a bit over scale for N. For short grass I don't use static grass but use Woodlands Scenics fine turf. I tend to use static grass on embankments, riversides and other overgrown areas.
I've had a lot of fun experimenting with static grass and the flyswatter, something I would not have tried if the expensive Noch Grassmaster had been the only option.
