Tomorrow is Halloween in the United States, and in some areas, it may be warm enough(opens in new tab) this year for trick-or-treaters to avoid covering their costumes with bulky winter jackets(opens in new tab). In other areas, however, multiple showers and thunderstorms(opens in new tab) may result in the unfortunate cancellation of trick-or-treat plans and require sheltering indoors.
If you are one of those who was tricked by the weather, we have a treat for you here on CTT. Today’s post features a roundup of some sweet tidbits about the materials behind some fan-favorite spooky season activities, including festive decorations, horror movies, and sugary desserts.
So, sit back, relax, and enjoy learning about the history and science of these Halloween traditions!
