In science we were learning about surface tension, what we had to use was: Milk, food colouring, cotton buds & soup.
It was fun watching the food colouring spread all along the Milk & dipping in the cotton bud into the milk with the soup on it.
It was hard to write up everything that happened & post it. (on my blog).
Next time I will try and finish faster so I can keep up with the rest of the class.
I wonder what experient.
