How can I communicate child labour to children ?

Shocked and angry with these images I decided that I would use one of our workshops (Gaffa tape and cardboard)  to re create a bag of coca pods one to one scale.  I estimated the height of this small child and worked out the size of the bag.  I left a hole in the top to put things in.  

Getting children to tidy up their toys and their friends toys in this bag in a school context would be a way to start a conversation about a difficult subject like child labour. 

Coca pod bag

becomes a way of starting a conversation with children about slavery

And an improvised toy box/ way of tidying up.
