Parker and I made this firefly craft yesterday afternoon. It requires a water bottle, some construction paper, pipe cleaner, packing tape and something for eyes (we used buttons), to make the firefly body. Then you put a glow stick inside. Here is a side view and a glow shot.
The pipe cleaner legs didn't work very well. I followed the directions and cut a length of pipe cleaner into thirds, bent them into legs, and taped them to the body. The tape doesn't prevent them from twisting so when we put it down the legs just twisted flat against the body. Parker didn't seem to care so I didn't worry about trying to fix it yesterday. If we make more, I'll have to give it some thought.
