  • Homemade “White Glow” Water Lamps. Simple DIY. Produces a “silvery white” light suitable for use as a low power lantern or nightlight. included in the video is a simple way to turn the project into a small Aquarium (betta fish tank) or terrarium. (starts at 2:40). project made using only a small plastic jar (or glass container) and a solar “pathway” light. could also be used as an ant/bug farm. (glue a piece of screen to the underside of the lid if making an ant/bug farm so the critters can’t escape). the solar pathway light and the jars are from a “dollar store”. great simple way to reuse/recycle and go solar.
