Last night the fire alarm in our bedroom started beeping signifying that the battery was low.  We have a high ceiling in our bedroom, so, the only way to get at the alarm is to use the ladder.  As I watched Jason set up and climb up the ladder, I couldn't help but be freaked out that the ladder might unlock and collapse.  Thankfully, he changed the battery with no problems and, luckily, I didn't see this video until AFTER the battery was changed.  (I may be wrong, but I'm pretty sure we have that exact ladder.)  [via digg]

Keith M. uploaded a few photos of the official Apple iPhone tool he received as part of his warranty package.  I wonder if Apple has these trademarked.

This credit card sized multi-tool should definitely come in handy when you need to open a can, cut things, screw things, measure things, and escape a burning building with no exits.  You could be the next MacGyver.

Worldmapper is a collection of world maps, where territories are re-sized on each map according to the subject of interest.

Here is  the world based on Total Population (2000):

and compare it to a map based on Carbon Emissions (2000):

Here is a very cool periodic table of elements which uses the top Google image result for each element.  Most of the images look legit except for Xenon -- She must be a famous Chemist or something.

Interactive Periodic Table, A Different Kind of Periodic Table Poster

I previously posted about a different kind of periodic table poster that is easy on the eyes.  Here is another periodic table that isn't as eye-catching, but very cool because it is interactive.  Scroll over, let's say "germanium", and find out everything you need to know (i.e., density, boiling point, etc.) about germanium.  It's a very handy tool.
