Look smart, get trashed, with this innovative cocktail mixer

Concept project serves up perfect drink every time

Enkaja cocktail mixer

Like a portable, waterproof, ridiculously durable speaker that you can wear on your clothing, this here is a gadget that once you realize is out there, you’ll very quickly come to the conclusion that living another day without it in your life is a day simply not worth living.

Three part cocktail mixer

It’s called Enkaja and the chemical elements-inspired concept gadget is a cocktail mixer created by Dublin-based design company Tatabi Studio.

Enkaja periodic table

A bit more specifically, it’s a modular mixer broken up into three circular bottles. There’s a bottom plug and top cap that attaches everything together. The idea is to allow the user to mix and test different formulas to create a new cocktail. One gets filled with a base (Sprite, Coke, Juice, etc.). The next gets filled with a spirit (Vodka, Tequila, Rum, etc.). And the last gets filled with a “touch” (Chocolate, Mint, Lime, etc.)

Enkaja mixing directions

Once everything’s in place, the user gives the Enkaja a good shake to create a perfectly mixed drink every time.

Planning a trip? Go watch an atomic bomb go off

Artist creates jaw-dropping photos for the post-atomic era

Clay Lipsky – Atomic bomb test in front of surfer

Planning a trip is like a second job. You need to book flights, pick between hotels, make a list of things to bring beyond just your awesome wireless portable speaker. By the time you’re done, you need a vacation from your vacation.

Fuck this shit

The most important thing that you absolutely, positively cannot forget to bring, though, is your camera. In this day and age, traveling isn’t legit till you post photos on Facebook or Instagram (no matter how many times you check in on foursquare, you f’ing hipsters!)

Guy on fire

This guy wasn’t on fire until someone posted it online – true story.

What if I told you, though, that you could take one of these pictures from a vacation and make it approximately 20 megatons better? (Physics majors will get that joke – everyone else, head to Google when you’re done reading this.)

Well, you can, and you can thank conceptual artist Clay Lipsky for the idea.

Lipsky created a series of portraits contextualizing the legacy of 1950s atomic tests and what we – the post-atomic era – would do with them if they were going on nowadays.

The vision he came up with was modern-day tourists gathering together at the “safe” distances used back in the 1950s, and the resulting cell phone photos that no doubt would end up being posted to Facebook albums, Tweets, Instagram, and the like.

Yeah, a little safer than that.

Check out the crazy realistic looking pictures after the jump.
