You Will Need:
Step 1. Start by spraying the inside of the jar with the frosting spray – this will help diffuse the light and give it a warm glow. don’t spray the lid though! it needs to be clear in order to work.
Step 2. Next you’ll need to take apart the solar lamp – apparently this can be a lot easier than it sounds, depending on what kind of lamp you purchase. Certain kinds can simply be unscrewed and the solar/battery pack remains intact, whereas others will require some reassembly with adhesive. See here and here for examples.
Step 3. Glue the solar cell, or the parts you’ve harvested from the garden lamp, to the underside of the jar’s lid, and you’re done! Close the lid, put your jar in direct sunlight, and it’ll glow all night long!
