A versatile decoration with endless applications, aqua glow in the dark gravel highlights features indoors and outdoors with a beautiful, bright aqua glow. From smaller installations such as vases, to creating stylish counter tops that glow in the dark, and even striking driveways flecked with glowing detail, glow in the dark gravel adds wow factor to your space, all without the need for batteries or mains electricity! Simply place the gravel where it will have maximum exposure to light allowing it to charge throughout the day and it will slowly shine with an aqua afterglow when darkness falls. This glow gravel is ten times brighter than traditional glow in the dark products such as children\'s glow stars, and the funky aqua pigment glows for longer than it\'s green and blue counterparts. A clever way to add a touch of colour and light to your home or garden night after night, glow gravel will glow for approximately ten hours a night, however this is wholly dependent upon the amount of light that they receive during the day and also placement; glow in the dark products show their best glow when viewed in pitch black conditions without any ambient lighting.
