How-To: World’s scariest Halloween prop

Forget cheesy yard tombstones, evil cackling pop-up witches, or ghosts that fly down from on top of the porch. Todd Harrison has put dual 110-decibel automobile horns inside his jack-‘o-lantern, which features a cute red button nose and buck-toothed smile to throw people off from how diabolical it truly is. And here’s the really wicked part: The horn is on a delay. Pushing the button causes the eyes to light up immediately, so the little tykes think, “Hey, neat, a pumpkin with light-up eyes,” and then go on about their tyke-y business, at least for a few seconds before the dual 110-decibel automobile horns go off and leave them traumatized for life. Genius! There’s video on Todd’s site. [via Hack a Day]

Update: Turns out this whole idea originated right here at Make: Online with one of Marc’s 2008 How-to Tuesday columns. So the evil genius has been in our midst all this time and I didn’t even know it. Sorry, Marc, and thanks for tossing me a clue!

    Just an idea but i bet more pants would be soiled if the horns came from behind (like carefully run into a bush behind the user), But this is great. Make should host a contest for the best movie of random trick or treaters being scared by our devices. As much as I love making devices I think a bunch of movies seeing little kids being taught not to press innocent looking red buttons would be worth the effort.

    In my side, I don’t know how to do and how to wear on Halloween. I have no time and my budget is limited. I prefer upload my own picture and send it out to friends and family with a message as a greeting on Halloween at
