Make your own sun jar. (a solar powered night light of sorts)
Not Martha has a great step by step tutorial based on the Sun Jar design by Tobias Wong.
List of materials:
- Ikea Slom jar, smallest size, about $3
- single Malibu brand solar garden light, about $10, from Lowes (see notes below for pictures of the specific one as there are a few variables)
- glass frosting spray
- some Blue Tak or sticky stuff
Not too crazy about working with electronics? You can also buy a similar version/nightlight from the Geek Gear Store.
They also have great ideas, if your so inclined, for recycling those floppy disks you feel so bad about throwing away.
