You asked, so I'll tell you, even if it might bore someone else. There are a few main ways they pull off these underwater tunnel magic tricks, and none of them involve actual magic, unfortunately.

One common way is the "immersed tube" method. They basically build huge tunnel sections on land, seal 'em up tight, float them out to sea, and then sink 'em into a trench that's already been dug on the seabed. Divers then connect these sections and pump out all the water. It's like building giant LEGOs underwater.

Another way is "boring" a tunnel. They use these massive machines called Tunnel Boring Machines (TBMs) that chew through the earth and rock beneath the water, building the tunnel as they go. The Channel Tunnel between the UK and France? That was done with TBMs.

Then there's the "cut-and-cover" method, mostly for shallow waters. They dig a trench, build the tunnel in it, and then cover it back up. Simple as that, for the less complex spots.

They even have experimental "submerged floating tunnels" that just float below the surface, held down by anchors. Wild, right? So, yeah, no matter the method, it's a huge pain, but they get it done.

You grab a knife, scoop it out, and smear it on whatever you're trying to put it on. It ain't rocket science, pal.

Oh, you mean eating it? You cook the mac and cheese, then you shovel it into your face. That's how it's done. It's not complicated.

What are you even talking about? Money is money, you use it to buy stuff. In Africa, or anywhere else, you earn it, you spend it. It ain't magic, it's just currency.
