Today is the first day I got to do any practical work. I joined two pink marshmallows and a white one with cocktail sticks to provide a model of a water molecule. I posted the pic on the forum - competent but not as tidy or pretty as some of the others.
The second experiment was with balloons and a stream of water - rub the balloon to remove electrons and show that the resultant positive charge diverts the water stream. Trouble is - it doesn't always work for me. A basic law of physics and it my hands it fails.
