Kangaroo vs Jumping Stilts
My mission is to find the planets ultimate animal adaptations and this time I'm on a journey into the heart of the Australian outback. To survive here animals must learn to live with next to no water, to find and store food in unique ways and to move around on the red hot sand but what animal will have ultimate adaptation. Kangaroos are Australia's most iconic animal, the largest Roo's can cover over twenty five
feet or eight meters in a single hop or 1.8 mitres high. Moving around in the outback can be seriously hard work but these guys make it look incredibly easy some kangaroos can hit a top speed of over 40 miles or 64 kilometres per hour using their long tails to help them balance, the hopping motion is over long distances is more energy efficient than running
but how do humans compare in the hopping stakes. Meet Graham he is Australia's number one Powerskipper using these bouncy stilts he can almost exactly replicate the bouncing motion of the kangaroos but how fast could Graham go using his bouncy Kangaroo like legsé We took him to a nearby airfield to find out. Obviously Graham doesn't have a tail which makes him struggle
with balance and stuff so we're going to give him more of a chance by letting him run. Graham you readyé I am. Right lets go. Graham has one run to try to get close to his target of 60 kilometres an hour. He's quick! Come on mate a little bit more. Come on graham, nail it.
That's about it, he's quick tho, he's quick! Come on Graham. He's quick, he is quick but we've left him ok. Graham looked pretty fast on the runway but how did match up to a kangarooé Graham hit an impressive a 31 kilometres per hour but unfortunately that's just half the speed that a kangaroo can reach but I'll tell you what a kangaroo can't do, is this. Anyway from one of Australia fastest animals to one of it's slowest.

twenty, thirty yards at a time, okayé Youjust get a good jog going, get familiar with your surroundings. Remember, stay on a flatground here.

Before you know it, and once you're comfortable, you'reactually going to be running in full strides. Alright. Now, don't get ahead of yourself,alrighté Once you actually start running, it's important to know how to stop. So, ifyou're jogging, make sure that you can slowly slow down, alrighté Alright, that's the basicson running. Next, I'm going to teach you how to stop, alrighté I'm Kevin Barret with ExpertVillage. Stay tuned.
