DAF DISCUSSIONS - MENACHOS 24
1. Barry Epstein asked:

The Gemara says that if one made a tamei sheet into a curtain, it is tahor from tumas midras but tamei from touching a midras. Since when can something make itself tamei?

2. The Kollel replies:

The Acharonim discuss whether it actually makes itself Tamei (and thus there may be a problem of Maga Beis ha'Setarim, touching in a hidden, covered place), or whether the more severe Tum'ah contains within it the lesser Tum'ah.
