The media has obviously avoided mentioning them. I assume there are a number of options. However, isn't it ridiculous to prevent people from bringing on tiny bottles of liquid like eye drops and lip balm? Or are the the substances when mixed even in tiny amounts that explosive? I'm afraid that even by asking this question I'll get a visit from the FBI.

why do they change between 'plus' and 'und' when adding. for example:
Eins plus eins ist zwei.
Zwei und eins ist drei.
Drei plus zwei ist fünf.
Zwei und zwei ist vier.
Eins und fünf ist sechs

2. How accurate do you think the answers you are getting are?

3. Do you look for confirmation elsewhere, after picking a "best answer" to your questions?

In my opinion this is a very poor site for answering scientific questions. I've read some answers here that look well-informed but which are not based on any established scientific theory. I'm not suggesting that people shouldn't propose alternative explanations to the accepted ones, but they should make it clear that this is what they are doing.

I'm not claiming to know all the answers to this questions, but I can recognise when someone is contradicting the science taught in universities all over the world (I have a 1st class honours degree in theoretical physics)

I am not claiming that the theories taught at university are absolute truth, but I expect that most of the people asking questions here are expecting something more in line with the ideas of Albert Einstein and Richard Feynman than those of Mark McCutcheon or Gene Ray.
