Pens and Needles: Disappearing Ink Tattoos!

For all you folks who identify with that old Shakespeare chestnut, "Hell hath no fury like an overprotective mother discovering a tattoo on her kid's arm (or worseth still, lower back)," stop your worrying. There's a new type of semi-permanent tattoo hitting the market that might just be the semi-rebellious rush you've been looking for. Created by the brilliant folks at Mass. General, these "smart tattoos" can be erased with a single, non-scarring laser treatment.

The process is actually pretty ingenious: the ink is encapsulated in tiny polymer beads measuring just 1-3 micrometers in diameter. The tattoos come out looking great, meaning that, unlike say a henna tattoo, it won't induce sneers from the other bikers in your gang. But when you finally decide that you don't really need that dolphin on your ankle, or the Chinese symbol for "trite" on your left shoulder, a laser treatment will slice the microbeads open, releasing the FDA-approved dye into your skin where it quickly (and more importantly, safely!) fades away.

Don't Have Space For a Christmas Tree? Decorate a Pineapple Instead

Christmas trees aren't for everyone. Some people can't fit a fir inside their cramped abodes, while others are turned off by the expense, or by the idea of bugs hitchhiking their way inside. Fake trees are always an option, but a new trend sweeping Instagram—pineapples as mini-Christmas "trees"—might convince you to forego the forest vibe for a more tropical aesthetic.

As Thrillist reports, the pineapple-as-Christmas-tree idea appears to have originated on Pinterest before it, uh, ripened into a social media sensation. Transforming a pineapple into a Halloween “pumpkin” requires carving and tea lights, but to make the fruit festive for Christmas all one needs are lights, ornaments, swaths of garland, and any other tiny tchotchkes that remind you of the holidays. The final result is a tabletop decoration that's equal parts Blue Hawaii and Miracle on 34th Street.

In need of some decorating inspiration? Check out a variety of “Christmas tree” pineapples below.
