This experiment is called Colour Pendulum because the pendulum makes beautiful oscillating patterns with colours. First, take a paper or plastic cup. Then poke a hole under it. Next, attach strings to it and hang it to a frame like in the video. The last thing to do is fill the cup with colours and let it spin. Watch the video to find out.

This is a colourful experiment with milk, food colour and dish soap. When you dip a cotton swab in dish soap and dip it in milk with food colour, amazing patterns appear. Please check out our video.
