Step 3Carve the popsicle sticks.
iImage Information

With your exacto knife, carefully carve the popsicle sticks. The popsicle sticks need to be carved and or hollowed as shown in the diagram below. The grey area is the part of the popsicle sticks that needs to be hollowed. As well, when carving "Layer 3," please note that the red dots on the three layers need to line up and that "Layer 3" is flipped over.
The hollow area should be carved about 1/2 to 2/3 of the way into the popsicle stick. It should be deeper than your wire is high.
