Don’t try this at home kids. But I seriously wonder for how long this could be considered relatively safe. I have a feeling that it’s little better than a much smaller bag that would only cover her head. More time in, more risk. That the bag has a bit more air to start with probably doesn’t make that much of a difference, because she’ll be rebreathing the same air in no time at all. Which is, as far as I know (which isn’t much), relatively safe only for a couple (3'ish) minutes. -- source link
