In my opinion, if you want a rainy day activity to keep the children amused then invest in some marbling inks.
The Art Cabin kids were mesmerised by the wonderful patterns, colours and prints they could achieve. The process is easy, but be warned… the inks will stain clothes, so wear an apron and cover the work surface with newspaper.
All you need are:
Marbling Inks, cheap absorbent paper (experiment with different types of paper too), a small tray filled with about 1cm of water, toothpick (or safe tool to create the swirls) and plenty of newsprint to cover the work surface.
Begin by placing a drop of ink in the tray then place/float a scrap peice of paper on top to soak up the ink, this will ‘prime’ the water.
Next, choose between 3 and 5 colours of ink that you wish to use. Only one or two drops of each colour is necessary as you don’t want your print to be too oily. Use a toothpick to gently create swirly patterns on top of the water. When you are happy with your pattern float a piece of paper on top of the water for a few seconds and then peel off gently and set aside to dry. Another print can be taken straight away, this will be less vibrant but still gives a pretty effect (this is known as a ghost print).
I have to say that the children in the Art club almost had a factory process in place churning out print after print, so do make sure that there is plenty of space for prints to dry.
