Oily Bubbles

Experimenting with water can be lots of fun; experimenting with oil and water proved to be a great hit with my second-graders this year!


I filled barbeque tin trays with oil (1cm deep) and mixed food colouring with water in small squeeze bottles. Students then squeezed the coloured water drops into the oil and watched them bead.



The results were beautiful!

 

 

I even had some curious students try and 'pinch' the water droplets to see if they could get the two liquids to mix.
