Glass Bottle Oil Lamp
Make a small decorative oil lamp out of an empty glass bottle with screw-on metal lid. It’s cheap, easy, and possibly romantic.
The lamp is filled with half water and half oil (or all oil if you like, but it’s not as pretty!), and will burn for several hours depending on its size. The one I made will burn for a good twelve to fourteen hours, perhaps longer (I haven’t exhausted it yet). All of the materials I used, I had lying around already.
There are endless variations that can be made. If you ever did the experiment in grade school with food-coloring-dyed liquids that float on each other due to different densities, you can turn this into a beautiful piece of artwork. Glycerine and rubbing alcohol work well. Cork will float between the water and oil.
