A cool video has emerged from Australia of a dad demonstrating how he built a massive swing for his kids, complete with a special hack that means he can also use it himself.
The footage, filmed near Sydney last Thursday, shows Jacob Strickling - creator of the popular YouTube Channel Make Science Fun - building the swing using fishing line and rope.
It initially can support the weight of his children but can't support his own, so he comes up with a clever hack so he can have a go too.
