Eclectic junk from the four corners of the ‘Net. And pictures too!
You can never have enough projects, right? Well I think that’s true. Tonight I finished my tutorial on how to hollow out a light bulb and re-use it for other things like art projects and science stuff. So don’t throw out that dead light bulb, make it into a salt shaker or something…
Now this is the sort of project I can sink my teeth into. What do you get when you cross a disposable camera flash with a bit of wire, and steel BB’s? A coil gun! Yeah… That’s the good stuff. Jeff provides plans and links to build your own weapon of choice. Have fun and be safe, if you can do the two at the same time. If not you can go as a pirate for next Halloween.
This struck me a being quite beautiful, go have a look at the full sized image on Astronomical Picture of the day.
In an attempt to make astronomy more popular, a Japanese company has come out with toilet paper that is printed with astronomical information. So far you can get either ‘The life of a star’ or ‘Beyond the zodiac’. ‘The life of a star’ tells the story of solar evolution, from a molecular cloud up to a planetary nebula. A translation can be found here. The second set, ‘Beyond the zodiac’, as they say, "… we represent the signs of zodiac and some astronomical objects toward these constellations. You can feel the depth of the universe with this ATP." I’d hope that you would feel the softness of the paper and not the universe but that’s another story.
As a teaching tool it will probably go a long way in increasing the awareness of astronomy among those who read while doing their business.

This is a big ‘ol slab of rock that is being pushed up from inside the volcano’s crater. There is a great time laps video of it showing the distance it’s grown since last November. The rate of movement is about 1 meter a day. I wonder how high it will get before it falls over or is destroyed by another eruption.
Good for nurses, even better for vampires!
It’s a hand held device that will produce an overlay that shows exactly where veins are located un the skin.
