Glow-in-the-dark candles might be slightly redundant, but we think they're pretty cool—and we're willing to bet your kids will, too.
These tea lights, available through Etsy, glow in the dark without even being lit. Imagine the spookiness when they're glowing and burning? You'll have the coolest house on the street. Their small size means you can display them almost anywhere for an eerie green glow.
