This is a short video of a magic knife slicing a water droplet in half. Except it's not really magic, because scientists had to go and ruin all the fun for us. You could have lied to us, you know. The government does it all the f***ing time.
The core of the blade is two 0.020-inch thick zinc and copper sheets. After forging it, it was cleaned with acetone, ethanol, deionized water and then air-dried with nitrogen. Then the researchers dipped it in "a 10 nanomolar aqueous solution of silver nitrate for approximately 20 seconds." Finally, they added the magic element, dipping it in a 1 nanomolar solution of substance called HDFT.
This seemingly magic material and manufacturing method can revolutionize biomedicine, allowing the separation of proteins in biological fluids "without troubling satellite drop formation."
Hey, I'm all for revolutionizing biomedicine and all, but I'm also all for cutting water balloons perfectly in half with a ninja sword. Think about how cool that'll look in slow motion! "I think you're missing the big picture here, GW." A MOVIE?! We could totally make it a movie!
Hit the jump for the video.
Thanks to Rev Dr Dom, who's never cut water with a knife but has cracked the crust on the top of crème brûlée before with a spoon. Equally impressive!
