I need some clarification here before responding lol.
Yes in primary school. We magnetised a sewing needle and stuck it to a cork which floated in a cup of water. It worked too!No, I'm lost all of the time (my cause is too). Have you ever made a compass?
I have, likewise in primary school. Have you ever made a sodium bicarbonate volcano model?Yes in primary school. We magnetised a sewing needle and stuck it to a cork which floated in a cup of water. It worked too!
Have you ever made a sundial?
Nah, I was right rubbish at chemistry. Glad to have moved beyond such courses.No although I can see how that would work. When I was still a school pupil we made something like a small erupting volcano using a porcelain plate with a small mound of potassium permanganate and some glycerol. Spontaneous combustion 🙂
Did you like spectacular experiments in chemistry?
