In those cases, however, the firefighters wear respirators and emergency medical staff is always on hand.īelief #4 - There are special fluids that can create a low lying effect from a regular fog machine.Īs far as I know, this is still fiction. The one exception I can think of to this rule is fire companies who use foggers to create simulated smoke for training purposes. If you want to create a hazy atmosphere throughout a room (to show off lighting effects in a nightclub, for example) you should purchase or rent a haze machine. You should never try to fill an entire room with fog. Only use as much fog as is needed to create the desired effect. Anything that reduces the amount of available oxygen in a room can be dangerous, this is why it's important to use common sense when planning a fog effect. Heavy use of fog in a poorly ventilated room can be dangerous for anyone, especially the very young, the very old and those who have asthma, severe allergies or other respiratory problems. Adding dye to your fog fluid will produce some interesting effects however, ruining the fog machine and voiding the warranty will unfortunately be among them.īelief #3 - Fog is dangerous to people who have asthma. If the fog is only being lit with a red spotlight, red is the only color it can reflect back.
The way to add color to a cloud of fog then is simply to change the color of light striking it.
Likewise, the droplets of glycol in a cloud of fog reflect back all the light striking them. To understand why this is not true, consider this riddle when snow melts, where does the white go? Is snow white because it's had white paint added to it? Of course not! Snow appears white because the ice crystals reflect back all the light striking them, in most cases that light is the "white" light of the sun. This is why it is so important to use only the fog fluids recommended by the manufacturer of your fog machine.īelief #2 - Adding dye or food coloring to fog fluid will produce colored fog. If the glycol in the fog machine does burn - either because of a faulty heater or (more likely) using fluid intended for another machine in your fogger - the result is a foul-smelling brown cloud. Actually, the heater in a fog machine converts fog fluid (a mixture of water and glycol) into a vapor that mixes with air to create a visible, white cloud. Despite this, many misconceptions remain about how fog works, how it should be used, even what "fog" really is! This week I'd like to examine some commonly held beliefs about fog - clarifying some and dispelling others altogether.īelief #1 - A fog machine burns fluid to make smoke. And because the surface of the pin was not as smooth as that of our main pick, in our tests it required more dustings of flour and more effort to clean.Artificial fog remains one of the most commonly used special effects in the entertainment industry.
Without tapered ends, however, the JK Adams pin isn’t as agile as the Whetstone pin, so it’s slightly awkward for rolling out round shapes. Our 10-year-old tester found this pin easy to use, too. Though the Whetstone pin is a steal compared with other similar hand-turned models, if you’re an occasional baker looking for something less expensive (or if the Whetstone is sold out), consider the JK Adams 19-inch Wooden Rolling Dowel. Compared with the surface of a basic mass-produced rolling pin, this pin’s hard maple surface has a smoother finish, which keeps dough from sticking and makes the pin easy to clean. Its long, tapered shape pivots easily, so it’s ideal for rolling perfect rounds of crust for pie and more-oblong shapes for cookies. In our testing for our guide to the best rolling pins, the timeless maple Whetstone Woodenware French Rolling Pin proved to be a superior tool and a great value.
