      Putting light through a prism and seeing all the different colours 😀
      .
      You can use a similar thing in “spectrometry” which helps you figure out what things (such as stars) are made of by the different colours they give off!

      Anything to do with Magnets and Electricity. That is really interesting how that all works.

      It’s more of an observation than an experiment, but I liked the BOOMERanG experiment. Partly because of what it did and partly because of its name.

      It measured radiation from the Big Bang and was the first experiment to find that the Universe is very flat (rather than curved like a ball or a saddle) and measure the total amount of energy in the Universe.

      Its name comes from the fact it was flown on a huge balloon at the South Pole. And the winds at the South Pole blow in a big circle, so that if you launch a balloon it dissappears and then comes back to you days later, like a boomerang.

      I still love the old school experiments of dropping a lump of sodium into water and watching it explode. I remember when my chemistry teacher put too much sodium in and it blew a hole in the ceiling!

      I used to take peoples blood and look at the white blood cells inside, they crawl towards bacteria, like this: https://www.youtube.com/watch?v=EpC6G_DGqkI
