There are still a few days before Halloween costume frenzy will reach its peak, but we think we have a winner. Forget all those Lady Gaga and Chilean miner costumes: We’re taken with Ben Heck‘s ingenious see-through portal t-shirt.

This high-tech costume makes it look like the wearer has a hole in his torso, thanks to a tiny camera on his back, and an LCD screen on his chest that shows the image captured by the camera. Want your own? Here’s a blow-by-blow video of how to build it. There are a few digressions into other projects, but we encourage you to watch through and get all the info you need to avoid the fate of being just another Gaga.

Many children are anxiously awaiting Halloween this weekend. But with all these sugary treats come a price: cavities. In fact, one out of every four children in the U.S. currently has at least one cavity in their baby teeth, a number that’s the highest it’s been in 40 years— and has been blamed on today’s sugary diet. Even worse, British researchers found that when kids consumed candy every day, they were more likely to be criminals when they grew up.

This Halloween, two Michigan dentists, Shawn Morris and Daniel Simmons, are encouraging kids to turn in their candy for cash. The mission is called Operation Gratitude—children will receive $1 per pound of sweets, so the dentists can collect a large candy stash. The candy, however, won’t go uneaten: The dentists will send it to U.S. troops stationed in Iraq so they can hand out the candy to local children.

So what is the incentive for candy-heavy children to turn in their loot? Hometownlife reports:

Youngsters who trade in their candy — a maximum of five pounds per child and total 1,000 pounds for the event — will receive a new Firefly glow-in-the-dark toothbrush and a goody bag of gifts. The youngsters will also be entered in a raffle to win one of three Nano iPods.

Along with reducing damage to young teeth, the candy collection also will benefit U.S. troops.

Good habits taught when you’re young could go a long way—especially considering that 80 percent of U.S. adults have some sort of gum disease. Plus, if cavities are left untreated, they can lead to permanent damage including loss of teeth and gum disease, which has been linked to stroke and heart disease. Seriously, more candy, more problems.

This year, Disco thought we’d get into the spirit of Halloween and dress up in a space suit. So we went to a costume store and bought a silver unitard for the occasion. But when we took the suit out of the bag, it smelled like a new shower curtain. Earlier this year, a national environmental organization found that shower curtains contained high concentrations of phthalates and released volatile organic compounds it to the air (which are all chemicals that the Environmental Protection Agency has recognized as hazardous).

Which would explain why the smell made us feel nauseous. We checked the tag to see what the unitard was made out of: 100 percent polyester, made in China.

So is this costume safe to wear today?
