How to make a mathematical breakfast

1

Place the knife vertically in the center of the bagel, making sure the tip reaches the bottom. Cut while turning, using the center of the bread as a reference. It is necessary to start with the knife horizontal and finish with the knife vertical.

2

Once you reach the halfway point, place the knife back in a horizontal position, with the tip pointing towards your body.

3

Rotate the bread so that it is upside down. Find where you started cutting the bagel and continue cutting, aiming to form an oval, similar to the previous cut.

4

In the center of the bagel, bend the knife so that it is first vertical and then horizontal.

5

Flip the bread again.

6

Cut the bagel in half, following the outline of the bread. Cut just like in step 1.

7

Flip the bagel and repeat the cut, just like in step 3.

8

Separate the bagel with your hands to form the chain.

9

Done! You have now cut a bagel mathematically in the shape of a Moebius band.
