  2. These teachers have been really stupid. Just take the first experiment.
    Looks like a liquid gas in a plastic bottle. -> The gas boils at room temperature
    -> it becomes 1000 times as big -> the bottle explodes. In a classroom,
    where 30 students sit? And the liquid gas which hasn’t vaporised flies through
    the room. GREAT!
    The teacher at 0:33 blows up the whole lab because he takes too much
    Chemicals and endangers himself and his students, the broken glass goes
    everywhere and the students hold their ears because it has been so loud,
    possibly damage at their eardrum.
    At 1:00 they build a sprinkler installation in the chemistry classroom…???
    Really???
    These teachers really deserve to spend much more time with their family (I
    mean lifelong holidays with that)
