When the ends are broken off and air puffed through it, it produces a chemical smoke that can be used in explosive atmospheres. Not great if you get it in your eyes, but its &#8220;safe&#8221;.  The airline passed me onto a dangerous goods packing form who offered to pack my tube for a mere $250, so i bought a new box of ten tubes and had them shipped as dangerous goods &#8211; for a total cost of half the price.  I ended up giving away the unused tubes, as i could not bring them back on the plane with me.<\/p>\n<p>I started looking at various <strong>miniature electrically powered foggers<\/strong> used in theatres. (I use a larger one from a local electrical shop Dick Smith but that is much to big to carry in my hand luggage) They all seemed rather expensive, but I found that a various companies make small fog machines to fit in the funnels of miniature electric trains.  I bought one made by Seuthe on eBay that started smoking at 9V and was rated to 16V.  It drew about 100mA, making the power consumption about 2 W.  It seemed to work fine with the fog fluid used with my larger Dick Smith fogger.<\/p>\n<p>More pictures to come.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I travelled by air to Rockhampton by air recently to deliver an introductory occupational hygiene course for a client.
