“I found the best method to make a realistic waterfall.
Lay out a sheet of cling film. Measure on it the height of the desired drop. Using clear sealant, starting from the “top” drag the sealant in close lines down to the “bottom”. as the sealant dries, use a fork to lift peaks away from the flow and create suitable turbulance at the “base.
leave to dry. paint the peaks and the turbulence with touches of white gloss paint.
remove the waterfall by pulling the cling film away (it doesn’t matter too much if some is still attached).
the waterfall can then be fixed in place by using a little more sealant at the top and bottom.
the rock face behind the waterfall should first be suitably painted and this will show through any gaps
it looks very realistic.
I’ve asked Dick for some pics.But when it comes to waterfalls:
And don’t forget there’s lots of stuff on ebay that sets just like water.
Keep ’em coming.
