É mentira como cavaram um buraco tão rápido olha as laterais do buraco estavam tão reto como botão rão fogo com pedra na água a tinta não era roxa e viro azul e a massa era fita de simento divido vc fazer igual com as coisas que usaram .
Ok at 6:50 you can see it's not actually just "hand-made" with no additional tools. The guy is spreading "paint" with his hand but is kind of faking it, and the paint line is straight, so they most probably used a roll. You can see that as well at the bottom of the pool, next to the stair. Definitely not a hand pattern.
