Rocket Booster Video of the Space Shuttle Discovery Launch.


From launch to a water landing, this stunning video shows you exactly what it would be like if you were duct tapped to the side of a space shuttle solid rocket booster. They get extra points from me for adding sound to the video. They must have bolted a transducer to the space frame of the SRB. RocketCam has more videos from past SST missions and even a few from some satellite launches.

Inkless pen made of solid metal

I wonder if this uses a low melting point alloy like Field’s metal.

The solid metal ‘nib’ consists of a metal alloy, that leaves a mark on most types of paper. If you use the sort of paper typically used in printers and photocopiers, the pen leaves a mark that looks as if it was made by a pencil. However the line will not smudge, and cannot be rubbed out. Since there is no ink, there is nothing to dry out, so the pen will work just as well in 25 years time as it does today. And of course it never needs sharpening.

Idea Globe or Polar Chalk Board

I love this idea! I’m going to be on the look out for an old globe to do this to.

Don’t have much room for a full white board or maybe you think chalk boards are outdated and take up too much invaluable wall space? Why not build yourself a handy desktop Idea Globe™!

Ingredients:

1. Used classroom globe (in this case my wife bought me one from target for x-mas).
2. Chalkboard Paint
3. Spackle
4. Newspapers
5. Gesso (with squirt of black acrylic paint).
6. Coat Hanger

Directions…
