Schlieren Flow Visualization is a method to see small differences in air pressure like those around a flame; essentially it allows you to *see* air. It is typically accomplished with super fancy mirrors that can cost upwards of $300. This instructable is about making a Schlieren Flow Visualization really cheaply and pretty easily. If you are curious about my failed attempts before I got it to work then visit my DIR Schlieren Flow page.
Here are all the components you need:
- A pair of rigid page magnifiers (this $9 pair on amazon was perfect).
- A cheap LED light, and something to attach it to, like a chair leg.
- A *DLSR camera and books to set the camera on or a tripod
- Cardboard+tape to make a stand for the magnifier.
- Candles, or something hot/cold or otherwise interesting to look at
*other cameras might work too but I couldn't get the effect to work with my point & shoots.
