I am curious about different ways to incorporate WAM into the spooky season. any ideas?

orange gunge is one, you could try incorporating a pumpkin like filling a pumpkin with orange gunge, and that's just the orange stuff.

Make green slime with xanthan gum, neon green food coloring, and tonic water. Do this under black light and watch that gunge glow!!!! IT'S ALIVE!!!!

Cool ideas so far! Might have to try some of these. I like the idea of using a pumpkin and themed gunge.
Keep em coming!

Hmm...maybe...

...as a nod to pumpkins, handfuls of fresh pumpkin guts
...as a nod to caramel apples, caramel sauce and cold apple sauce
...as a nod to trick or treat chocolate, chocolate syrup
...as a nod to bobbing for apples, head dunks in something sticky and sweet
...as a nod to witches' brew, a concoction of various and sundry sticky sweet substances
