The Mephisto Spiral is a neat toy that gives the illusion that you can continuously pull the two spiral halves apart.
You used to be able to buy one from grand-illusions.com , but it seems they no longer stock it, unfortunately.

The Mephisto Spiral was patented by Thomas Klipfel of the Union Wire Mattress Company in the year 1900:
