How Digital Light Processing (DLP) works
How Digital Light Processing (DLP) works
How Digital Light Processing (DLP) works
Digital Light Processing projectors use a chip that is covered with tiny mirrors that tilt back and forth. When the mirror is tilted one way, it reflects light out through the front of the projector, creating a bright pixel. When the mirror is tilted the other way, the pixel is dark. In this video, I explain how DLP works and show a macro-scale model.

Measure the mass of an eyelash with a DIY microbalance

Measure the mass of an eyelash with a DIY microbalance
I built a microbalance based on a design by Paul Grohe: http://www.youtube.com/watch?v=n90whRO-ypE
It is has a precision of about 5 micrograms, and I measured a single eyelash at about 35 micrograms. The balance is built from an analog panel meter that is controlled by a servo loop which optically monitors the meter's position. Adding mass to the meter's needle requires that the servo loop add more current to maintain the needle's position. This additional current is read, and converted to a mass value.

How a horn amplifies sound (hint: Impedance matching)
How a horn amplifies sound (hint: Impedance matching)
A horn-shaped speaker is louder than an equivalent speaker without the horn. This fact doesn't violate physics because the horn is acting as a matching device between the speaker and the air around it.

The science of wineglass tears (or wine legs)
The surface tension of water and the evaporation of ethanol produce an interesting effect in a wineglass known as "tears" or "legs". The process is caused by the Marangoni effect, which explains how toy soap boats work among other interesting things.

Color-changing Zinc Oxide -- and submit your questions for Ben
Submit your questions for Ben in the comments section for a Q and A session next week.
Heating zinc oxide with a blow torch causes it to turn from a white powder into a golden yellow. The process reverses when the substance cools back down to room temperature. The heat drives out some oxygen from the ZnO lattice, cause some locations to have a Zinc metal ion. This disruption in the lattice is able to absorb more blue and violet light, causing the overall substance to look yellow.
