Do you have a longer driveway or a really boring driveway ? Or maybe you have a path, walkway, or trail that needs some glitter. Check out these little glow in the dark stones from Jinan Chenghao Tech. Obviously from China but grab a handfull of these little guys and scatter them around to cause a really neat glow in the dark path.
They can be put into your concrete mix when pouring an exposed aggregate driveway or even used in your fish tank.
