Professsor Temple's Transtemporator 2 Inch Round Button

Many is the time in one's adventures when one detects one has made a critical misstep. Perhaps saying the wrong word, mistaking an important person's name, failing to set the safety switch on the Atomic Fractometer or stepping into empty air instead of onto the deck plate one intended to tread on. It was precisely for this reason that Professor Temple invented the Transtemporator. This new and exciting breakthrough allows the user to temporally step back from whatever has just gone amiss. Simply set your time interval and presto. It was particularly useful in un-inventing the outer-gods summoning device he never actually built.
