How a hole on a beach becomes a tsunami tower 🌊 If the sea ever disappears… don't go and look. #tsunami #whatif #engineering #3danimation #survival

If you dig a hole on a beach to hide from a tsunami, you have a bathtub. But the first wave pours in, fills it to the top and you barely scramble out. You can't hide down from a tsunami, you have to go up. So you shovel the sand into a tall hill and climb on top. But the wave comes faster than you can run and washes the hill away. So you pour concrete walls and build a solid tower, but a solid wall catches the full push of the wave and it cracks wide open. So you leave the ground floor open and the water flows right through. This is a tsunami tower, but the rushing water digs the sand out from under your columns. So you drive long piles deep through the sand into the hard clay below. And the wave brings boats and cars that smash into everything. So the columns get thick and round and the junk slides right past. But you only get minutes of warning and your whole family has to climb. So you wrap a wide ramp around the tower and everyone runs up fast. But some waves get taller than a three-story house. So the roof goes 30% higher than the biggest wave they predict. And if the sea ever pulls back and the beach goes empty, don't look. Run up. The ground floor isn't unfinished. It's empty on purpose. So the wave goes right through, add a blanket, a radio, and a crab who climbed up with you. Congratulations. You have built a tsunami tower.
