This DIY will show you how to make a solar-powered LED jar light like Tobias Wong's Moon Jar, which was a Nice and New of mine a while back, which would set you back $40 if purchased. It's pretty darn cool — it "collects" sunshine during the day, so you can use it as a lamp when the sun goes down.

Supplies:

• 1 Ikea SLOM Jar
• 1 Solar garden light
• AA rechargeable battery (if it doesn't come with the garden light)
• Blu-tack
• Screwdriver
• Utility knife
• Glass frosting spray or tracing paper

Here's how:

1. Using the utility knife, rip out the innards of the garden light.



2. Fill the jar with the innards, using the Blu-tack to keep them together. Keep the solar panel exposed to the clear side of the glass lid (top), with the underside serving as a base for the rest of the components, and the light sensing diode should be visible from the lid so it can receive enough light. Make sure not to break the pieces by pressing too hard. You may have to play around with the pieces to make them fit.



3. Either frost the glass with the spray, or cut a piece of tracing paper to size and put it on the interior wall of the jar. For a different color of light, get colored tracing paper.



4. Lock the lid closed. Done!
