Turn Film Canisters Into Colored Glow Sticks for Light Painting

If you have some translucent film canisters lying around, you can turn them into DIY glow sticks for light painting photography. Fuse three of them together into one translucent tube, stick a small flashlight into it, wrap it with a colored translucent sheet, and voilà, you have yourself a cheap and simple glow stick. It’s a way to add some thickness to your light painting “brush”.
