Máté Csipszer made this charming clock from old bike parts. The body is the hub of a wheel and the numbers are shaped pieces of bike chain. The hands are pieces of cut plastic. Does it work? Máté says "that it runs well but in a different way not as it did on the road."
How delightful! You can see more photos at Recyclart.

1. The Moon is freakin' huge, we're talking ginormous. A natural satellite of the earth should be something closer to 30 miles in diameter, Luna is over 2000 (that's bigger than Pluto).
2. The moon doesn't have a magnetic field, but it's rocks are magnetized.
3. Some moon rocks date back 4.5 billion years and there's even one that was dated 5.3 billion years old (that's a billion years older than the Earth.
4. Moon rocks have also been found to contain processed metals like brass and mica, and uranium236 and neptunium237 (those have never been found to occur naturally).
5. The Moon also appears to be freakin' hollow!
