      I have done lots of studies, tested lots of hypotheses using statistics but not really conducted experiments as part of work in the way you might think of them.

      In high school (back in the 1980s…) there was a lot of concern about acid rain.
      I entered a ‘science fair’ – not sure if they have them here. School children conduct studies or experiments, then write them up on posters and present to judges.
      My parents let me grow loads of bean plants. They were in individual little pots and some plants got watered with water with neutral pH (7) and some with mildly acidic water and some with highly acidic water. Then I measured the plants as they grew to look for effects of acid rain. The effects weren’t nearly as dramatic as I’d hoped, but had a great time. And finishing off those posters was the first time I stayed up all night working (I was 14). I got an award for the best agriculture-related science project.

      Hiya, I don’t think I’ve done any proper science experiments since I did chemistry A-level at school. But I like to do fun experiments at home, like putting methos in a coke bottle like this guy:

      I remember the school experiment of putting a tooth and a chicken bone into a well known brand of cola drink and seeing the effect it had (dissolved / softened) – no fizzy drinks for a while after than one.
