🔴 ¿Qué es el Islam? 🔴 El Islam no es solo otra religión, es el mismo mensaje predicado por Moisés, Jesús y Abraham. 🔵 Islam literalmente significa "sumisión a Dios" y nos enseña a tener una relación directa con Dios. 🔴 Nos recuerda que, ya que Dios nos creó, nadie debe ser adorado excepto Dios, también nos enseña que Dios no es como un ser humano o como nada que podamos imaginar. 🔵 El concepto de Dios está resumido en el Corán como: { Di: "Él es Al-lah, Uno. (112:1) Al-lah es el Absoluto. (112:2) No engendró ni fue engendrado.(112:3) Y no hay nada ni nadie que sea semejante a Él". (112:4)} 🔴 Convertirse en musulmán no es darle la espalda a Jesús. 🔵 Por el contrario, es regresar a las enseñanzas originales de Jesús y obedecerlo.

Have you made an oblique cut on the second part?

Obrigado por assistir ao vídeo, e obrigado pela sua mensagem, no caso da garrafa eu só queria mostrar o poder de sucção da bomba,

@@yousefmousavi7346 entendi. Eu preciso fazer uma, mas p garrafa pet. Você teria alguma idéia?

Para fazer isso, você pode colocar uma válvula de soro, após criar um vácuo, feche a válvula de soro e desconecte a bomba.

I made an oblique cut inside the rubber piece with a razor blade, the size of the hole on the handle is as desired

I do not know how the laboratory filtration device works

The cut should be diagonal, you don't need to cut the black cap completely, just enough to allow air to pass through it, I think one centimeter is enough.

@@yousefmousavi7346 thx bro i will try it

Привет, чтобы кольцо внутри шприца оставалось фиксированным и не двигалось при всасывании, потому что, если оно не зафиксировано, всасывание не будет.

@@yousefmousavi7346 спасибо

I will try it too

Thank you for watching the video, I will try to include all the details in the next videos.

Las incisiones en las arandelas negras deben ser diagonales.

Hola, las rodajas deben ser oblicuas.

@@yousefmousavi7346 you are welcome 👍

Эти разрезы необходимы для всасывания и выпуска воздуха.

I wanted to use simple tools

You probably did not cut the black rubber pieces correctly

¿Qué no entendiste?

Thanks for comment

The cutting of the black piece must be done accurately, the cutting must be oblique.

​@yousefmousavi7346 I've cut it properly, but why won't mine suck?

Thank you for watching the video, I will try to show more details in the next videos. Thanks for comment.

Maybe you didn't cut the black plastic tape correctly, the cuts should be diagonal.
