Instant laser coffee
Instant laser coffee, I’m not sure if a 35W laser would work (this is a 2Kw) but I’ll try and experiment later – [via] Link.
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 TO – Make a rotary evaporator on a budget
Tenderbutton would be proud- In case you need to create a monolayer of lipids inside a spherical flask and don’t to spend $3000 on a commercial rotary evaporator, this is the design you need. Justin Ingram and I set out to build such a device from things found around the lab for a small fraction […]
Listen to rats laughing…
Turns out rats are ticklish, and they laugh… It might even work using a bat detector like the one we showed you how to construct here @ MAKE… I supposed you could potentially tune in to the rat giggling… Aristotle declared that humans are the only animal to laugh, but then, he never saw this […]
Using a data logger to record the temperature inside a beehive
Forrest M. Mims III has an article on using a data logger to record the temperature inside a beehive in the latest Citizen Scientist – Over the years I’ve done some consulting for the people at Onset Computer Corporation, the makers of Hobo Data Loggers and various related products. Consequently, I’ve accumulated a nice collection […]
Floors and furniture… made from cow manure
There isn’t a how-to (yet) – but this seems like an interesting new particle board material… Home-buyers of tomorrow could find themselves walking across floors made from manure. That’s no cow pie-in-the-sky dream, according to researchers at Michigan State University and the U.S. Department of Agriculture. They say fiber from processed and sterilized cow manure […]
An adventure in relative time-keeping
Tom sent in this letter to Physics Today, he used an atomic clocks to show his kids they’d get an extra 22 nanosecond from relativistic time dilation… I’m a little skeptical since the difference would be super tiny, but have a gander – it’s pretty neat – I enjoyed Daniel Kleppner’s Reference Frame about the […]
Solar hot air balloons
Teamdroid writes – Everyone knows about hot air balloons. A great big sack filled with hot air that floats as if by magic in the sky. I’m sure most people think that the air needs to be heated by great honking propane torches to obtain positive buoyancy but that just isn’t the case. With a […]
