PRACTICAL ELECTRICS (1921-24) was Gernsback's second magazine aimed at the electricity enthusiast. In 1924 he changed the focus to include chemistry, under a new title, THE EXPERIMENTER. Under this title it ran until 1926, when it was merged into SCIENCE AND INVENTION. The covers of the earliest issues already show the gosh-wow futurism that permeated all of Gernsback's technical magazines of the mid and later 1920's. By the end of 1922 they were running full-color covers, and continued doing so until the magazine merged out of existence.
