rainbows in a jar

We've been doing school light today and playing with rainbows instead 
a little bit of colour science, with both of us enjoying ourselves...

then later on a family pub quiz after her ladyship had gone to sleep... from up and down the land our family troop gathered  at the virtual Three Crowns to demonstrate our ignorance, catch up and share a drink...  a  good way to end quite a full on and stressful week :-)
