Non-Obvious Halachic Points that might be Very Relevant (please do not clutter)

[cynic]

You are not allowed to learn if you have to go to the bathroom, similar to davening. Machlokes about being miharher.

be very careful about choosing threads to read when you are in the bathroom, remember

anything you say, can (and will!) be turned into a halachic discussion

Those papers with Divrei Torah that are distributed in Shul, may not be read while the Tfilla or reading of the Torah.

Or

in the bathroom

[gozalim]

how about yogurt lids

[Sammy82]

how about yogurt lids

What exactly are you doing with yogurt lids in the bathroom?

[HudZ]

how about yogurt lids

They cover yogurts.

[Chuchum Ainer]

Prob the "I've never heard of it before, and it just seems wrong me..."

Hey that's the whole point of the thread! It's in the title.

Even if you sell chametz, you are not allowed and the sale does not work on "challah" meaning challah that you took off from dough (hafrashas challah). Therefore you must get rid of it before pesach.

[SuperFlyer]

If moving in somewhere in the middle of Pessach, it is preferred that bedikas chomets is done (by someone else if needed) before Pessach.

[SuperFlyer]

If one will be say in a rented apartment just for Pessach, it is wise to include in the chomets sale, also any room or cupboard marked as 'sold'.
This way, without knowing what the place looks like, you have a place to put toasters or whatever unexpected problematic items one may encounter.

Bedikas Chametz doesn't end when you find the last piece.

Some of these are incorrectly assumed otherwise:

If you are consuming whole wheat matzo for the mitzva, be aware that if your matza was made by milling the bran and the kernel separately, you may need to subtract the bran from the shiur. This means practically that you need to add 15% more on your shiur to have a full kzayis.

It is my understanding that most matza bakeries mill the whole grain together, but that there are some who do it separately

[SuperFlyer]

If flying during Pessach and a meal is offered,  often it won't be Kosher for Pessach.

If possible,  try ordering a fruit platter.
If the ticket has not been ordered yet, have Kavono not to be Koyne the ticket.*

Not accepting the meal does not help, as allocated already.

The fact that a special meal is in fact, only a request and not an obligation to the airline, does not help.

*I know it sounds weird, but I told

Some of these are incorrectly assumed otherwise:

Debatable. Many hold that Chametz Matzos are not chametz gamur and may be sold.

[SuperFlyer]

Debatable. Many hold that Chametz Matzos are not chametz gamur and may be sold.

...and some hold that everything can be sold.
...some hold that machine matzo are chomets....

[Mr. CC]

...and some hold that everything can be sold.
...some hold that machine matzo are chomets....

No one holds that machine matzo is chometz (there are those that say it's 'chometz gamur')

[SuperFlyer]

No one holds that machine matzo is chometz (there are those that say it's 'chometz gamur')

The difference being?
Please, I'm  trying to keep this thread as clean as possible.
