So I’ve sort of been testing out an idea that I’d been thinking about…
Baking wasp nests that have yet to fully dry.
Right now, I’m using a toaster oven that has racks and settings so that the whole thing doesn’t melt. The lowest temp it shows is 250 F but the oven I had allowed it to go lower so it only warmed the air.
So far I’ve baked it for about 40 minutes and it’s mostly done now! Gave the inside of the tube a quick puff of the hairdryer because the glue in there hadn’t dried yet, and it’s all set!
You could probably bake it at a higher temp, I wasn’t sure when the plastic and string would start to melt/burn though, so I didn’t push it.
Not a bad use of 2 hours! 
Cheers!
