Microballoons

[Redgum]

My little dust squirter that I use for checking wind direction ran out of powder, searching on the internet I came across Microballoons, microsperes or glass bubbles,they have many names. Amazing stuff, OK you can use baking powder which does the job but will occasionally clog. Enter microsperes, amazing stuff, so fine it almost behaves like liquid, does not clog and it just floats in the air. For years I just threw a bit of dried grass into the air to check wind direction but these little dust squirters really give you an advantage when its not blowing a hoolie. Even on the calmest of evenings you will be surprised how much air drift there is.
