Exploring Liquids: An Experiment

Here’s a fun experiment you can try using the contents of your kitchen cupboard. Explore the effects of different densities and learn about refraction, viscosity and the planet Jupiter. You’ll need five different liquids; I used golden syrup, dishwashing liquid, water, alcohol and vegetable oil. I also used some food colouring to make it easier […]

Make Your Own Spectrometer

Note: This experiment involves sharp objects and should only be performed by children if under supervision. As long as care is taken, this is a fun experiment with effective results. It can be done without the razor blades, but the results are not as good. Spectrometers are used, like prisms, to spread light out into […]

Air Pressure and Coke Cans

I recently did a piece on measuring the speed of light using your microwave. Well here is some more physics you can play with in your kitchen. This time let’s create a vacuum and then use it to crush something. I like crushing things. Don’t we all? What you will need: A regular drinks can […]

Measure the Speed of Light Using Your Microwave

Astronomers studying star formation, like myself, use telescopes that can see though the pretty, optical exteriors of nebulae into the dark interiors where very cold dust radiates in the submillimetre and microwave regimes. Microwaves, fall on the electromagnetic spectrum, between radio waves and infrared waves. They are usually around the size of a few centimetres […]
