PHYS 1060 001: How Things Work

• String tied (hooked) at both ends between two rods. I just want to show that a string alone will produce only very weak sound. Also, would like to have two sticks,which one is twice as long and heavier than the other.

• Ohm's Law
  ( To show how sensitive the MOSFET is to a tiny amount of charge. The procedure is I can touch the gate of the transistor with one finger and either the + or - of the power source with the other finger, and thus switch the current ON and OFF. Thanks a lot!)

• The cylindrical glass container (about 1 liter) with water in it, a wristwatch to be submerged inside the water, to show that the numbers vanish when I hit the total internal reflection angle. Thanks.

• Transistor Amplifier

• 1. Several masonary nails (high carbon steel), a vice, a really hot blow-torch, pliers, and a beaker of cold water. I want to harden a nail by heating it yellow hot and quenching, then trying to bend it. I then want to anneal a nail by heating it yellow hot and letting it air cool slowly, then bending it without breaking it. 2. A magnet and a cheap 18-8 stainless steel knife (the magnet should not stick). If you have no knife that a magnet won't stick to, then a spoon or a fork will do. Thanks a lot!
