Splinter can be a very sensitive boy, so I wasn't sure how he'd react to harvesting the silk from the cocoon, an act which inevitably involves the death of the pupa. They are either killed during the process or in preparation for it (think about that before you buy a silk purse or shirt). I chose the latter method, baking the cocoons in a 200-degree oven for 20 minutes prior to boiling (and while the kids were out of the house). Those puffy white cocoons looked just like a sheet of meringues.
Hopefully the next, and perhaps final, silkworm report will be about moths hatching out and creating new life in the form of hundreds of eggs. I say hopefully, because I'm not sure I found a dark or quiet enough place for the pupa to morph. We should know by the time December rolls around.
