Mixing Colours

We are talking these days about light and colour.

Today we tried a colour mixing experiment.

We have 6 cups, 3 filled with coloured water (primary colours: red, blue and yellow).

We wonder if we can get water to move from one cup to another along a folded tissue?  We are optimistic that it will!

We wonder what will happen if the colours do travel along the tissues and mix.  Will red + blue = purple, yellow + blue = green, red + yellow = orange as we predicted?

We are leaving our experiment over the weekend.  We can’t wait to see what will happen! 

It worked ok but we think we had too much food colour in each pot.   We want to try again with less food colour and more water.

Bingo! It worked so much better this time!
