We will be using solder. Solder contains lead, which you don't want in your body. Don't eat or drink while working with solder. Wash your hands after working with solder. Do not touch your face while working with solder.

• Really nice iron bolts for making electromagnets often have a dull black finish.

Do not build a Tesla coil, because it is too dangerous. You may want to learn how a Tesla coil is built, just so you can be sure to avoid making one by accident. Also, Tesla coils can damage computers that are more than six feet away, so be extra careful that you do not operate one anywhere near a computer!

Boy Mechanic from 1912 has some interesting projects. Some are dangerous, though.
