Zippy Zip-line takes the form of a big zipper, which unzips as you hurtle down its length.
Being a double interlocking teeth dependant mechanism means Zippy Zip-line has several advantages and applications that a conventional free-fall zip-line cannot achieve: it's a much stronger arrangement, meaning
that it's safer and can carry heavier loads; it can act like a flexible funicular railway. ie made to run uphill as well as downhill with the provision of a motor inside the zip casing; its rate of descent and ascent can be controlled; it can be used to traverse a valley where it hangs slackly under no tension.

Yes, I have had trouble with zippers. What gave it

You could make it go faster by "spreading" the un-zipping ends.. |
