YouTuber Brainiac75 suffers for science by taking a viewer request to touch the spikes formed by exposing ferrofluid to an extremely powerful neodymium magnet. He also shares some history of the substance.
Ferrofluid is a major skin irritant, so it's best not to replicate this at home. The ferrofluid quickly starts traveling up the ridges of his finger and around his nail. He repeats the touching with a rubber glove on, and the ferrofluid leaves a permanent residue on the fingertip of the glove. It's a little nerve-racking to watch because if he gets the fluid too close to the magnet, the force will be too strong for him to keep it from smashing into the container of ferrofluid.

The Giant Magellan Telescope is a marvel of engineering, and Dr. Patrick McCarthy explains the years-long process to make an optic mirror that costs over $20 million.
Anthony Atala, director of Wake Forest University’s Institute for Regenerative Medicine, is developing techniques to 3D print human organs for transplant using an individual’s own cells as the “ink.” That way, the transplanted organ won’t trigger the patient’s immune system to reject it as a foreign body. From National Geographic: (For example,) to create an […]
A Scottish team of animal biotechnologists announced this week they successfully introduced human stem cells into sheep embryos. Perhaps one day we will all have our very own baaing organ donors. The team are currently allowed to let the chimeric embryos develop for 28 days, 21 of which are in the sheep. While that might […]
The web is vast, and while there’s room for everyone, competition is stiff when it comes to landing on that first page of a Google search. That’s why developers aren’t afraid to spend exorbitant amounts of time and money on search engine optimization (SEO) to ensure their sites rank higher than others. However, not all […]
Many of us enjoy the aesthetic of vintage electronics, but trying to use most hardware from the 1950’s isn’t necessarily practical. This is especially true where speakers are concerned. While most of us can appreciate the old-school feel of retro speakers, they have a hard time matching the convenience and power delivered by today’s Bluetooth speakers. […]
Python is one of the most popular and versatile programming languages used by developers today, making it an ideal first choice for those looking to kickstart a career in programming. While you could go back to school or sign up for a pricey coding bootcamp, you can learn the essentials of coding with Python at […]
