He’s the author of numerous O’Reilly and Make: Books titles, including Building the Perfect PC, Illustrated Guide to Astronomical Wonders, Astronomy Hacks, and Illustrated Guide to Home Chemistry Experiments. I asked if he would […]
In 1927 Dr. Thomas Parnell at the University of Queensland heated a sample of petroleum pitch, also called bitumen, and poured it into a glass funnel, with a sealed neck, set in a ring stand. Three years later, in 1930, he broke the neck off the funnel and set it aside. It took eight years for the first drop of pitch to fall. The experiment has been running continuously ever since, and has produced a total of eight drops to date. The man shown in the photograph is Dr. John Mainstone, who is the experiment’s current custodian.
In this Boing Boing Video, PopSci columnist and author of the splendid and high-recommend Theo Gray’s Mad Science, explains how electrochemical machining (ECM) works and shows off a rig he put together to do ECM in his shop. The entire how-to can be found at popsci.com. Carve Steel with Saltwater, Electricity and a Tin Earring […]
Cymatics explores the amazing effects that sound has on liquids and some downright bizarre effects on non-Newtonian fluids
Julie Yu, a post-doc at San Francisco’s Exploratorium, has a really good collection of unusual home lab activities on her page, including a home column chromatography experiment using common materials, which is the first of its kind I’ve seen.
A research team at the Fraunhofer Research Institution for Electronic Nano Systems (ENAS) in Chemnitz, Germany, led by Prof. Dr. Reinhard Baumann, have developed a 1.5V battery that weighs less than a gram, is less than 1mm thick, and can be printed using a process similar to that used in silk screening. The new type […]
Science Fair project FOR THE WIN! According to a piece on Wired Science, a 16-year-old high school student, Daniel Burd, from Waterloo, Ontario, has figured out a way to quickly decompose plastic (like that used in shopping bags) by letting bacteria eat it. He presented his findings at the high school science fair. The Record […]
