Left Over Larry

I am going to call my project Larry Leftovers because I made it out of leftovers from other projects.  I started with an empty crayon box, a tuft of orange wool, a red pom-pom, two blue LEDs, two 2023 coin cell batteries, and a battery holder with an on-off switch.  I used a glue gun, needle nose pliers, hole punch, and tape.  The parts were in different places in my house (sewing room, garage, and kitchen.  I gathered everything together on the kitchen table and completed it in about twenty minutes. After gathering everything, I didn’t have to get up to find something.  But this involved planning.  In the classroom, I think all teachers do this when they plan a project – they think ahead about what materials to have available so they won’t have to go get something after the kids get started.  The kitchen table is one of my favorite places to work because it is well lit by a big bay window and I can listen to music while I work.  At school I have good lighting (unfortunately no windows) but no music.  Hmmm, should I get a little radio?

I used a couple of tricks I like with the LEDs.  First, I use a black Sharpee to mark the negative lead so that when I bend it, I can still identify it.  Then I take the needle nose pliers to pinch each lead and wrap it into an “eye” so that I can thread wires through them.  This eliminates the need to solder – an advantage when working with little kids.

I put the coin cell batteries in the battery holder and attached the wires to the positive and negative leads of the LEDs.

 I used a hole punch to punch holes in the crayon box and drew eyes and mouth on the box.  I glued the orange fleece on the inside of the box using the hot glue and reinforced it with tape.

I glued the red pom-pom on the front of the box and voila, Larry Leftovers!
