I had an idea last Fall that I implemented shortly before we left to spend the winter in Florida. I returned recently & checked to see if everything had survived intact. SUCCESS!
I live in the country & it can get pretty dark out there at night. We have security lights for the rare times we have to go to the out building at night but I've found that the light isn't aimed quite correctly so it doesn't go on right away if I leave by the side door. Rather than asking hubby to add another light, I made a solar path marker. So far there's only one because I wanted to test it first.
I used a glass jar (probably a pickle jar), a cheap dollar store solar light that's smaller than the jar & some aluminum foil. The strip of foil---glued to the inside of the jar & lid---made it more reflective.
I hot glued the solar panel---minus the stake part---to the bottom of the jar so when I turned it over, the solar panel could pick up the sun's rays thru the glass.
When I screwed on the lid, it was pretty much weather resistant. I buried it level with the ground just off the edge of the concrete by the workshop. At night it gives off a soft glow in the grass.
We can mow right over it & unlike stepping stones, it's almost invisible during the day. The plan is to collect more jars & bury them at intervals across the yard so I'll have a lighted pathway to the workshop. I think they'd also be great placed randomly in a flower garden.
