I used to try and teach ants how to swim, although I was never successful. I also used to enjoy focusing sun light on straw in order to burn it, and I think that in reality that would have been my first ever experiment.
My first experiment I remember was with cabbage water; and using the water from boiled red cabbage to test whether things were acidic or alkali (the opposite of acid) – the purple cabbage water went red with vinegar, and then yellow when adding cleaners!
