Or just use a very sharp knife and do not chop but slice, without pressure.
Edit: The knife used in the video is pretty dull.

Time to hit that mead stock.

There are some schools like this in Germany as well. Usually children that have issues like attention deficit disorder or do not fit into a normal school (problem child) will attend to such a "Forest school" (Waldschule). There are studies that it benefits development as the change in scenery from the busy city life helps the children adjust. It is definitely not very common and children still need to attend regular classes.

To say it has a flair of "anti science" is a bit far fetched as these schools often teach a lot about the local flora and fauna, do stuff like looking at water samples under a microscope or take earth probes. Sure it is not super scientific, it probably compares to what most kids would do as boy scouts - except it's part of the school's education program. For some kids this approach is better at fueling their scientific curiosity than in a regular school environment where they have many other issues to deal with.

Why would anyone do that in the first place?

Very many people are completely oblivious, they spam their Facebook, Instagram and other Social Media feeds full with information on a day to day basis. Completely unprotected.

Usually they don't have any anti-spam plugin for their email client (and probably wouldn't even know how to install / configure it). Windows (and OS X) both have a great user interface which lulls the user into believing he has control of his system, when in fact he is not exerting any security and control on his own behalf.

I always thought there were 4 controls for helis? Rudder pedals, cyclic, collective and throttle - or does it depend on the model?
