  • Mirror That Only Reflects When You Smile

    This video showcases the creation of a unique mirror that only reflects when the viewer smiles. The mirror utilizes a sheet of liquid crystals that turn opaque when a voltage is applied and clear again when the voltage is turned off. By connecting the voltage control to an app that detects joy or smiling, the mirror's reflectivity can be controlled. The creator demonstrates the mirror's functionality by smiling and holding the expression, allowing them to see their reflection, and when they stop smiling, the reflection disappears.
