I know it’s a little late, but Ari and I each came up with a way to make breathing forbidden for Jews over Passover. We came up with reasons why the carbon dioxide in the air would be chametz and therefore unfit for Jewish consumption during those 8 days (as opposed to non-kosher elements during the rest of the year which are ignored if below a certain percentage, chametz on Passover is forbidden in any amount).

Anyways, here’s mine:

During Passover, there are people all over the world eating bread (aka: chametz). The bread is broken down into glucose (among other components) which is turned into energy via glycolysis and then the Krebs cycle. With each turn of the Krebs cycle, carbon atoms from that glucose are incorporated into carbon dioxide (a waste product of the process), which will be breathed out and join the atmospheric pool.

Now before you panic about this, there is a solution to the problem. Observant Jews purchase milk and eggs before Passover, because it is forbidden to use non-chametz that was created from chametz (in that case, chicken and cow feed) on the holiday. Therefore, the trick to getting around the carbon dioxide problem is just to acquire a bottled air supply before the holiday and breath that during the following 8 days. Any garden variety air will do, the trick is just to find a place to store it…

Be nice to Ari and maybe he will share his method as well.
