Of course, to have a double, you first start with a single, which you might remember from here. The first time was so much fun, 'Sketchy' Andy Lewis – AKA 'Mr Slackline' – and his crew (often known as the Moab Monkeys) decided they had to do it again, and they brought Wingate Motion along to film it. So, let's answer some of your 'how the heck...' questions.
It’s about 150m high
It wasn't easy to build – in fact, it took 80 volunteer riggers two full days to pull the 7,000m (21,000ft) of parachute cord, rope and webbing together over the canyon. Once it was up, though, the fun was on. For those that couldn't walk slackline-style to the Spacenet, a different sort of entry was required.
How do you get there? Walk... or hang
The two Spacenets are strung together with a 'dynamic highline', something rarely seen, even in the world of slacklining. It's a slackline with two moving anchors, which makes it even more challenging, as the movement of the line beneath your feet becomes even less predictable.

All together, the two Spacenets weigh just 100kg but they are able to support a crowd of over 15 people on there, with each of the seven 'legs' of the Spacenets monitored with dynometers to track the load, which peaked at 15Kn (that's Kilonewtons, converting to about 1,529kg of force.) How strong is it really? Strong enough that this guy decided to turn it into a big rope-swinging exit for a BASE jump.

So where is the Spacenet going next? As much as they'd like to rig it in space, they're not sure they'll ge the appropriate permission from the International Space Station, so the team is setting its sights on 3,000m cliffs in Norway, or between buildings in Dubai. All we want to know is: how much does it cost for an entry ticket?
