ZipLock bags have been proven to prevent explosions.

I have a particular problem with the baggies. Zip top bags of this exact size are simply not available in my part of the world. There are zip top bags, sold by the size of their sides (not volume), none of them are square, and obviously they look different and therefore dangerous to the astute TSO at the frontline.

I´ve tried all sorts of compensation tactics, and been scolded for:

1. Using a 23 x 17 cm baggie (wrong size, not square).
2. Using a torn baggie (old one I got in the US and reused until in tatters).
3. Using a durable non-disposable baggie which holds 960 mLs (I measured!), is transparent and has a real zipper on top. (not zip top baggie = bad).
4. Using a sandwich baggie (no zip top, but exactly 1 L volume, square size, like a US ZipLock).

My problems only decreased after SSSS disappeared and I stopped taking the baggie out.
