A spectrometer is a device that splits light into all of the different colors it's composed of that can't be seen with the naked eye. It does this by using a prism to refract or bend the light.
Believe it or not, that's what whipped cream looks like when viewed through a spectrometer.
You can do this with just about anything, and it's hard to tell what other common household objects can produce colorful images like this one.
Here's how Jeffrey made his cheap, DIY spectrometer out of a VHS video case, USB webcam, and a DVD.
First, he cut a small slit in a piece of thick black card paper and folded it to fit into the VHS case. Next, he split the DVD into layers and cut out a small rectangle, attaching it inside the lens hole on the webcam with epoxy.
After removing the infrared filter from the camera, he attached it inside the box, using Velcro in case it needed to be readjusted.
Here it is in action, using spectral matching to tell the difference between two different types of olive oil.
