Make sure your light bulb is not a fluorescent one to avoid contact with hatful toxic fumes. Always reuse regular light bulbs.
Using a screwdriver or scrapper remove the bottom metal part of the light bulb. It my look rigid but it will easily be removed.
Using your screw driver you will have to break the inner glass part as shown in the image. Then remove it from the light bulb. After that wash the light bulb and dry it with tissue paper.
Put the plant of your choice in the empty built then fill it with water. Use the aluminum lid to hold the light bulb still on the table. I used the lid from honest tea bottle.
Final assembly of the repurposed light bulb. A pretty glass plant holder 💡
