I mentioned a while ago that we are experimenting with smoke generators for the wingtips of Bloke's and Rodney's airplanes.It was quite hard to find a useful composition because we were really just faking it. Then Rodney got in touch with a guy who sells the colored dyes and he gave use useful formulations which we are now messing around with. Today we got the first smoke composition that actually worked. It generated smoke on a small scale and we were very excited about the results. I am here closely supervising the test burn. Still a very long way to go.
