A while ago I bought an insect fogger and filled it with glycerin and water and got some really nice smoke effects. Today we visited Yarndley’s bush and took the fogger with - filled with pure vegetable glycerin this time.
It’s a 5-10 minute walk down a hill to the beginning of the forest which was preserved for posterity by some forward thinking people.
The insect fogger is powered by a gas cylinder and is reasonably safe to use. There is a metal screen around the ‘flame’ area of the fogger and it sits pretty stable - but to be even safer I made sure I set it up on the solid walkway.
The first thing to do is to check which direction the air is moving so after a few puffs I got an idea where to move to once the smoke was flowing. The results were quite satisfying. I’ve included some images with no smoke for comparison.
