Or just use a lighter
Fleabay it is then. Plus I will try the chalk.Search on ebay for "dropper bottles" and take your pick.
The advantage I find with chalk (you can get chalk used for marking lines such as a builder would use and it comes in big bottles) is that against many backgrounds you can actually watch it drift for quite a considerable distance. In forestry against dark trees you get to watch the wind for maybe 30 seconds or more as the chalk drifts away from you. In light winds I find this useful. It is also why I prefer chalk to the dragons breath stuff as it is not so easily seen as the bright white of the chalk.
Agreed, must admit mines been playing up since getting moisture in it.
Vicks nasal spray bottle.
Mrs saw it on the stairs one day when my jacket was being washed, shoved it up her nose and squeezed for all she was worth........
Managed to stop laughing just long enough to call the manf of the powder to make sure it was completely inert and harmless as the powder was for an industrial application......
Needless to say the bollocking lasted many days lol
Embrace your inner child, and go with bubbles, you will be a happier person for it! Ze Deutsch 'Pustefix' bubbles are ze uber bubbles, but them crazy Danes have some super dooper soap mix too nowadays, and lego inspired wands to get many wee bubbles a-moving and indicating. Both recommended, both also offered in 1 litre eco-friendly refill bottles for topping up your handy, smaller pocket deployment system!!
