Science
DIY science is the perfect way to use your creative skills and learn something new. With the right supplies, some determination, and a curious mind, you can create amazing experiments that open up a whole world of possibilities. At home-made laboratories or tech workshops, makers from all backgrounds can explore new ideas by finding ways to study their environment in novel ways – allowing them to make breathtaking discoveries!
How Wood Hardness is Measured
In fact, there are a now a couple of different tests, but the traditional method is known as the Janka hardness test, named for Austrian wood researcher Gabriel Janka, who invented it in 1906. The test measures the force required to embed a standard-sized steel ball (of 0.444in/11.28mm diameter) exactly halfway into the surface of a standard-sized sample of the wood
Math for Makers
I’m excited to see that Greg Borenstein has launched Makematics, a blog that covers his own exploration of advanced math topics that are found in new creative applications by and for makers.

How-To: New Paper from Old Paper
Though we’re constantly moving toward more electronic and less paper-based communication, we’ve all got paper we don’t need laying around, be it junk mail, newspaper, receipts, magazines, paper bags, books, or whatever else. If we’re lucky, it ends up in the recycling bin. What about giving old paper new life by making it into new […]
