Build a Christmas Tree Glow Salt Circuit and learn in your classroom or home.
Start by putting something down to protect the surface of your table. I used a large sheet of parchment paper.
Draw your design with a pencil. Your light will be the star at the top of your tree.
Test the LED.
Detach the LED bulb and set it at the top of your paper. Set the battery and alligator clips at the bottom of your paper, after making note of the positive and negative connections and ensuring you have them lined up properly. Attach the alligator clips to paper clips.
Now start putting the glow glue on your paper by carefully tracing the line you drew. You want a nice thick line of glue.
Add glue ornaments in a different glow glue colour if desired.
Make sure you have an extra thick line at the beginning and end of your line (base of the tree and top).
At the base add your paperclips, at the top set your LED legs into the glue.
Sprinkle a generous amount of salt over the whole glue line making sure to get it everywhere.
More than likely your bulb won’t come on yet. Add another line of glue over the whole thing. Plus another sprinkle of salt. Continue until your LED turns on!
