The mind likes a strange idea as little as the body likes a strange protein and resists it with similar energy. It would not perhaps be too fanciful to say that a new idea is the most quickly acting antigen known to science. If we watch ourselves honestly we shall often find that we have begun to argue against a new idea even before it has been completely stated. Wilfred Batten Lewis Trotter (1872-1939) English surgeon.

Magnetic Pick Up
YOU WILL NEED
A piece of paper
A paper clip
Thread
Clear tape
Scissors
A strong magnet
HERE'S HOW
Cut a paper kite shape about three inches long and attach a paper clip to one corner. To the opposite corner, tape a piece of thread about eight inches long. Tape the other end of the thread to a flat surface. Use a strong magnet to pick up the paper clip and extend the string to full length. Hold the kite between your fingers and slowly move the magnet away from the paper clip. When you release the kite, it “flies,” unattached to the magnet.
WHY?
Magnets have a magnetic field, an invisible force that attracts some kinds of metal. Metal objects within the magnetic field do not have to touch a magnet to be pulled by magnetism.
