Darkest material ever

"Scientists created a material so dark they couldn’t even measure it. British company Surrey Nanosystems developed the original Vantablack in 2014, which was then the blackest material in the world. But they’ve outdone themselves with the new Vantablack."

"Vantablack is a substance made of carbon nanotubes and is the blackest substance known, absorbing up to 99.965% of radiation in the visible spectrum."

The name comes from the term "Vertically Aligned NanoTube Arrays".

Tips from the article:
♞ Focus on the task at hand, not the end result.
♞ Don’t create your experiment and judge it at the same time.
♞ Break the experiment down into the smallest tasks possible.
♞ Remember: these are experiments. Not full-time business ideas.
♞ Don’t repeat yourself.
