The discovery that standard Edison bulb bases screw perfectly into 16 oz. PET bottle caps was a profound moment for me. Fun fact: Standard female garden hose (FGH) thread will also fit a light bulb base (and, I suppose, by inference, a 16 oz. PET bottle).

I found these mini floodlight/reflector bulbs burned out in an old china cabinet. I reclaimed them by hollowing out the bulbs using the familiar method, etching off the metal coating inside with extra-strength white vinegar, and fitting them with white (salt) and black (pepper) 16 oz. screw-top pop bottle caps with holes drilled in the center. Unlike a regular pear-shaped light bulb, this mini-floodlight type will stand upright on its own without help. I’ve done this before, but never with these cute little R14 bulbs.
