Me being the person I am, I decided to do some experiments with sticking needles in Halloween candy, because I had some mini Twixes that I was going to eat anyway lmao and twix/snickers are the most popular Halloween Needling Candies. I was primarily concerned with: how hard is it to put a needle in candy, how clean does it come back out, and can magnets find it
First of all, it's clear why they're the most popular, you can pretty easily stick a needle in a Twix if you get it started then press it against a table. If it's in the wrapper you're not gonna crush the edge too bad and frankly kids are gonna beat this candy up anyway.
I'm curious what one looks like after it's been getting beaten up in a bucket with other candy for an hour or two, but I'd rather not go to jail if I get caught walking around the neighborhood alone with a twix with a needle in it in my possession. But if I remove the needle right away, it comes out....about 90% clean I'd say. The needles in photos are always suspiciously clean, but a lot of it (for a Twix anyway) does kinda get wiped off by the cookie part. You should expect some candy stuck in the eyelet though, but most people's photos aren't really clear enough to spot that kinda detail.
The main thing I realized though is, these parents waving magnets over the candy? Fucking absolute waste of time. I grabbed the strongest magnets I have, my big fuck off harbor freight magnets that are hard to even pull off of my toolbox, you don't feel SHIT waving them above a needle in a Twix bar.
Tomorrow I might see what a razorblade in an apple does with a magnet, I'd imagine that'd be more effective maybe, but if I do that right now then I'm committing to eating an apple and that's just not how my evening is going.
