 What I’ve got to do here is really grip just with my thighs and let them take the strain and just balance with my arms and try and protect my family jewels. 

 
There’s water at the bottom of this gorge. But you can’t guarantee it’s drinkable. You have to find out first where it’s come from. It’ll only be totally safe if it comes from an underground spring. 
 
What I’ve got to do is just keep following the stream up here to find where it stops. Yeah, it’s still going here. And yeah, look, it’s dry up there. And this is what happens. When it rains, it’ll pour down here. When it’s dry like now, you’ll see this, like, natural spring. And this is the source of it. And look, if I dig down into this, however much water I take out, it’s just going to keep refilling. This spring water has filtered through the rocks to emerge as clean water. That means it doesn’t even need to be boiled. And what’s happened here is that all this water just gets cleaned naturally as it filters through all the rock and the sand. And it’s 100 percent safe, this stuff, to drink. And the great thing is however much of it that I do drink, this thing is just going to keep welling up and filling up.
