Hi Michael and Les
Excellent! Glad it has worked 100 per cent for you. Never thought of a
fogbow in my breath steam. But I couldn't get the sun that far over. Been
meaning to try the experiment outside but due to the lack of sun I might
as well use a candle. Does this mean we could get a section of rainbow,
too? I wonder if the steam from the kettle would contain droplets big
enough!! In the summer I have seen sections of rainbows well below the
horizon with me looking down a bank and getting that critical angle. I've
also seen a section of rainbow on the level roughly 5 foot or so off the
ground. Natural ones with natural raindrops that is, no cheating! it's
just a matter of working out the (42 deg) angle from the shadow of your
head to the bow. .
The good news for me is I've found a caterers urn and it works and it
doesn't automatically switch off! So I can steam the building out! :) I
can also make a bigger cloud and can leave it on longer without boiling
the thing dry. :)
Going to have some fun but first we have got to get the sun out!
THEN we'll try the ole Moon. :)
Kevin
PS I must urge both of you to use the kettle idea if you have got an
old-fashioned one.
Any one will do, though!
I've also made iridescent colours as well using my breath with purplely
and green.
