BASF rattleback pen

Do you know what a rattleback is?
Well, once I bought a piece of plastic made to have that type of behaviour. Nowadays I can't find it, but yesterday I discovered a everyday device that has the same behaviour.
I happen to have a ballpoint pen made by Schneider in Germany for BASF. And this pen has the behaviour of a rattleback. That means that if it is spun in the "wrong" direction, it will stop and reverse its spin to the preferred direction.
Just look at my short footage of the phenomenon:



I will not try to explaing what happens, but the Internet is full of material if you look for it. On the other hand some questions appear, like;

• Is Schneider aware of this ?
• Was this behaviour specified by BASF?
• Or am I the first to observe this?

Leucochloridium paradoxum in Strømmen

Last Sunday a movement caught my attention in my garden. It turned out to be an example of Leucochloridium paradoxum, that is a parasite in a snail trying to get the attention of a bird so that the bird can eat it! Well, I had my Android availabel, and the result is this short film:



As I showed my discovery to the neighbours I certainly reinforced their impression of me!
