Making a disposable paper cup
So, we take a sheet of paper and (if at hand) scissors.
Then we fold the sheet of paper in such a way as to cut off the unnecessary part to obtain a triangle.
Cut off the unnecessary part.
After we have a triangle, take the right corner and transfer it to the left side of the triangle.
We do the same with the left corner, but to the right.
Then we lay the front upper part of the front side in the resulting hole.
Fold the rear upper back.
Straighten the cup.
A cup is ready and you can safely pour a drink there.
But it should be noted that if you want your cup to remain dry for a long time, then you need to do everything as well, but using several sheets.
