So some food colouring diluted in water, eyedroppers, and paper towels = FUN! We experimented with mixing colours (yellow + blue = GREEN) and discovered that mixing all three colours leaves us with 3 shades of brown.
Jambin loved this activity - he spent probaby 45 mins doing this while I sat at the table with him, knitting and nursing a lovely cup of hot coffee. Last night I sticky-taped them up on his bedroom wall in the shape of bunting. They match his red sheets perfectly.
