Fireflies in a Jar

Step 5:

You can use shrink tubing to protect the NE-2 legs from shorting. I usually use it when I make these, but I left it off so that the connections would be obvious. This is a safety step --but given the protective jar, it's a step that can be skipped without a lot of risk of catastrophe. If you used a fairly stiff wire and separated the NE-2 legs, they should stay that way.
