      This depends on your interests. For example, would you be interested in chemistry or physics or engineering ..
      If it was me, I would definitely like to do some engineering experiments at home..

      Hi George, I love this question, there are many interesting experiments you can do at home! The most interesting is obviously whatever you find most interesting!
      A cool experiment to do is the test of the Leidenfrost effect: It explains the strange behaviour of water droplets at very high temperatures. A nice video covering it is this: https://www.youtube.com/watch?v=Sgk4sY9Xn1U&t=42s In the same channel you’ll find many other cool experiments.
      Please be careful and follow all safety instructions!

      Hello! I love the Marvin and Milo series that the Institute of Physics have,

      It’s great for physics-related experiments. The Alka-Seltzer rocket is a lot of fun, but make sure to follow the instructions safely and don’t put your head right over it…

      One cool experiment is to extract DNA from strawberries – All you need is strawberries – (extra for tasting is essential!), water, salt, washing up liquid and surgical spirit and something to filter it with like a coffee filter paper or some cloth.

      You can use surgical spirit (propan2-ol) instead of the ethanol described here

      As a chemist I’d be remiss if I didn’t suggest growing crystals, they are beautiful things and easy to grow with a little patience

      Excellent question!
      Testing the pH of things around your kitchen is a really fun thing to do. When I was a Cub Scout leader during Covid and were stuck at home we held a Cubwarts camp and I (Dr Di) was on zoom teaching the potions class, we had so much fun.
      You can use red cabbage as your indicator – see https://edu.rsc.org/primary-science/red-cabbage-rainbows/4011608.article
      or you can use turmeric, we tried both.
      Take care when testing cleaning products and you don’t need much of each!
      Have fun but be careful!
