objets d'mud

Believe it or not, this beautiful ball was made with nothing more than mud and a cloth, and it can be done by children.

Click the pic for a small gallery of other gorgeous mud balls. You can also read a bit about what William Gibson had to say about mud balls, or read how to make a mud ball yourself. (See the bottom of the article).

Homopolar motor

Make a 10,000 rpm motor in less than a minute using only one drywall screw, one 1.5 V alkaline cell, six inches of plain copper wire, and one small neodymium disk magnet. (Any metallic magnet which has a north pole on one flat face and the south on the other will do.)

Wow.
