Transparent 150mm paddles in 3 primary colours and 3 secondary colours with 3 textures. An excellent way of demonstrating the tricky concepts of colour mixing - hold all the colours together and you see black. Mix red and blue and you get purple. Red and yellow makes orange and blue and yellow makes green.
Contains 10 x A5 sheets of light sensitive paper. Place an object on the paper and expose to the sun for 2 minutes. Soak in water for 1 minute and the result is a clear white image on dark blue paper. No chemicals required. A great way of illustrating the process of photography.
