An Electric Water Heater
A simple electric water heater may be made as follows: Procure two sheets of copper, each 4 by 6 in., and place pieces of wood or other insulating material at the corners to keep them about 3/4 in. apart. Bind them with cords, or, if the wood pieces are large enough, use screws so that there will be no contact between the plates. Attach wires to the plates with solder as shown, and make connections to a plug. Pour water in an earthenware jar, place the plates in it and turn the plug in a lamp socket. Do not use a metal vessel.—Contributed by G. Henry Jones, Sylacauga, Ala.

Frosting Glass
Procure a piece of flat iron similar to an iron hoop, bend it, as shown in the sketch, to make a piece 3 in. long and 1-1/4 in. wide and file one edge smooth. Sprinkle some fine lake sand over the glass, dampen the sand and rub the smooth edge of the iron band over the glass. It requires only a short time of rubbing to produce a beautiful frosted surface on the glass.—Contributed by M. E. Duggan, Kenosha, Wis.
